Futaba 6J Six-Channel 2.4 GHz S-FHSS Radio-2011/12

Author: Jennifer Orebaugh


Edition: Model Aviation - 2011/12
Page Numbers: 67,68,69,70,72

I DECIDED to review the Futaba 6J Radio System from the
perspective of a beginner, because I am one, and for others who
are looking for a reliable, easy-to-learn transmitter.
Right out of the box, the biggest difference with this
radio system is that it has Frequency-Hopping Spread
Spectrum (FHSS) technology instead of Futaba Advanced
Spread Spectrum Technology (FASST). FHSS transmits on
a narrow-band frequency, but changes the frequency of
transmission hundreds of times a second. The receiver has
to know the frequency-changing pattern to switch to
different frequencies in the same order and time frame as
the transmitter.
FASST hops to different frequencies every 2 milliseconds
and is not compatible with FHSSS technology.
The Futaba 6J
Radio System is
an asset to any
type of aircraft
flown whether
the pi lot is a
beginner or more
advanced.

The center knob on the
transmitter controls flap trim
and hovering pitch fine-tuning.
Both functions are inhibited
unti l turned on within the
function menu. The knob can
also operate a sixth channel.
The trainer switch is on the left
side of the transmitter. When
the 6J is used as the instructor
transmitter and the trainer
switch is activated, the model is
controlled with the signals from
it, and will work with a Futaba
FASST or FHSS transmitter.
Below: Shown with the included
R2006GS receiver and the switch
harness, the Futaba 6J is an affordable
radio system at less than $200 with highend
programming functions and modes.
The control sticks can be adjusted to
make it comfortable for the modeler to
hold and operate the transmitter. The
stick tip can be turned counterclockwise,
while holding the locking piece, to
lengthen or shorten the stick.
Below: Uncluttered, clean, and simple,
the Futaba 6J faceplate is easy to
navigate. Minimal buttons and a large
LED screen make it easy for a
beginning modeler to learn how to use
a transmitter and fly.
Inset: The data input lever is used to
change the values of various functions,
including changing the model name,
setting dual rates and exponential, and
fine-tuning the trim. Below the data
input lever is the select key, which
displays the submenus and values for
the current function.
Below: The trainer/buddy-box micro-type cord input is on the
back of the transmitter box and easily accessible. The 6J can be
used as either the instructor or student radio, with three modes
available, depending on the student’s ability.

The R2006GS S-FHSS receiver, shown connected to
throttle, elevator, and rudder controls, is on a diversity
antenna system, which maximizes the signal reception and
allows the modeler to fly trouble-free. It also adapts to the
transmission mode (S-FHSS or FHSS).
I could not link to or fly other airplanes or helicopters with my
transmitter if the aircraft were set up with FASST system
receivers.
Easy learning began with the instruction manual. I read it before
I took the system out of the box. From the beginning, I found the
instructions handy. I thoroughly reviewed the clear and concise
material. When I was ready to go through the settings on the
radio, I reread each section step by step.
One of the first sections in the manual is a glossary, which is
helpful for someone who is unfamiliar with some of these terms.
They were in logical order, but I would have preferred for them
to be in alphabetical order for quicker access, with possibly a
note at the end of each definition with other relevant terms.
I never felt lost in the terminology and there were plenty of
photos, as well as illustrations, for each section. The instructions
began with an introduction to the transmitter controls, then
moved on to radio and receiver installation, range-checking the
radio, the linking procedure, what each alarm and warning bell
meant, and then finished with programming the system. Although
some of the initial steps were already completed at the factory, it
was nice to have the instructions.
I was ready to program the radio and pick
up and handle the transmitter. The first thing
I noticed was that there was no antenna. The
6J transmitter antenna is internal—a nice
upgrade. I felt at ease knowing this radio
would have full range without the
bothersome antenna.
The weight of the transmitter was a
concern, and I wondered how well I could
handle it and if I would need to purchase a
transmitter tray. I was surprised at how
lightweight and comfortable it was to hold.
The four AA batteries hardly added any
weight. A five-cell NiCd/NiMH pack could
also be used. The angle of the transmitter
made it easy to grip.
I was also worried about being able to
control the sticks, but the 6J fit nicely in my
small hands. Although I’m still deciding
whether to pinch or thumb-fly, I felt
comfortable trying both ways. The length
can be adjusted, and the instructions are in
the back of the manual.
The airplane I planned to fly with my
transmitter is called a Flutter-By. It only has
rudder, elevator, and throttle controls, plus
optional LED lights for night-flying. The
designer labeled each servo wire, making the
connection easier to figure out.
The manual included directions for
setting up and connecting the receiver and
“relinking” (the receiver is linked at the
factory). When I attempted to link, the
receiver flashed a red light, meaning there
was no signal. After unplugging the battery
and plugging it back in, the receiver light
once again turned green and stopped
flashing.
I also did a range-check with the 6J’s
special power-down mode. It’s a great
opportunity (especially when you’re flying a
model for the first time) to make sure the
equipment is properly working.
To complete the range-check, follow the
instructions in the manual: walk 30 to 50
paces from the model while simultaneously
operating the controls on the transmitter, and
have an assistant stand by the model to let
you know that everything is working as it
should.
Walk back and start the engine (if it is
internal combustion, make sure the throttle
stick is all the way down), and repeat the
steps. Run the airplane up at various throttle
speeds, but remember not to try to fly the
model in this mode, although it does revert
back to full-range mode after 90 seconds.
The blue light on the front of the model
will blink and beep when you begin the
range-check. The word “down” also blinks
on the LED screen, so there is no way to
mistake that the transmitter is in this mode.
Now is when the controls and program
functions come into play. The instruction
manual explains each program’s function
and the purpose of each button on the front
of the transmitter.
The buttons on the front of the transmitter
are simple, and the faceplate is uncluttered.
To the left of the LCD screen, the top button
is the mode key. This button is used to view,
select, and change the different program
functions and settings on the 6J.
Press and hold this button for one second,
then scroll up or down through the different
settings, using it and the bottom left button,
which is the “end” key. (There are arrows to
the left of both keys that indicate these
buttons can be used for scrolling through
different settings.) The transmitter beeps
when selecting from screen to screen.
To the right of the LCD screen is the data
input key. Use this button to change the
values in each programming mode. Use the
bottom key on the right side (the select key)
to set the function/mode.
The Parameters (PARA) menu is the first
one that I set up, using the mode button for
access. The aircraft type (airplane or a
helicopter) model selection, and name,
throttle-cut, mode settings, and a total reset
are programmed here. The manual does a
good job of taking the modeler through each
step, numbering the steps, and providing
photos of each screen.
Selecting the aircraft type was slightly
confusing. At first I wasn’t sure (when the
model type was blinking) whether I needed to
press a button after using data input to select
the correct type. I expected it to stop blinking
once I selected the right type, but it didn’t.
The 6J has memory for 15 different
models, and additional models can be
assigned different channels. It can also name
each model in memory which is nice (choose
MODL for the model-select function).
By pressing “select” while in the MODL
menu, then using the data input button above
it, you can scroll through the alphabet and
numbers to designate a four-character name
for your model. When finished, hit the end
button.
Because my model is the Flutter-By I
named it “FRBY.” Creating a name similar
to that of the airplane makes it easy to
remember which aircraft is assigned to what
channel.
All data in the transmitter can also be
reset to factory settings if needed. This
comes in handy if the airplane crashes and is
no longer flyable, or you want a fresh start.
This setting is under the model reset (REST,
in the PARA menu). It only impacts and
resets the model that is on the screen, not all
in memory, so if you have 15 models only
that particular model is wiped out.
I knew I wanted to be in fail-safe mode
(everyone should do this for safety), and the
S-FHSS mode on the 6J offers fail-safe on
all channels, so models added in the future
will automatically be set to fail-safe.
Whether this mode or FHSS mode is chosen,
the compatible receiver adjusts accordingly
to the signals from the transmitter.
S-FHSS also offers a battery fail-safe
mode that is activated as a factory default. If
the battery voltage drops below 3.8 volts, it
moves the throttle servo to a predetermined
position.
The throttle-cut is a nice factory setting
for internal combustion engines, but can be
switched to ESC for electrics. The throttlecut
button is on the front of the transmitter.
When used and set, it beeps and flashes the
word “MIX” on the LCD screen. The
throttle does not accelerate or decelerate
when it is set. To turn it off, press the button
again. This is a great accessory, especially
for a new modeler.
In terms of dual rates and exponential
(expo), the definitions in the manual are
vague. Beginners may need to do some
online research for better understanding. The
manual states that dual rates are: “… the
ability to change the travel distance of a
servo or servos, affecting the overall travel
of the servo(s). Thus, decreasing the
percentage value for a given servo will
reduce the travel amount of the channel
respectively.”
In other words, dual rates change how far
the control surfaces can move with respect
to the stick movements on the radio. A
lower percentage value for dual rates is
better for the beginner, producing gentler
movement. (Overcontrol is common with
someone just learning to fly.) A higher rate
will allow the flier to do rolls and flips and
be more aggressive.
Exponential “affects the travel of the
servos around their center in relationship to
stick movement.” It increases or decreases
the sensitivity around the central or neutral
stick position. Futaba transmitters use
negative expo (the opposite of other
transmitter brands), so make sure you are
going the right way. Positive expo increases
sensitivity and negative reduces it, making
the movements softer and milder at a lower
percentage. Too much (positive) can make
the airplane react too fast, while less expo
(negative) makes it easier to control.
The easiest way to test what feels right to
you, and the functions of dual rates and
exponential, is to have your model setting on
the table or workbench and play with the
controls. See how different settings on the
transmitter affect the movements, especially
in high and low rates.
Other function menus include End Point
Adjustment (EPA), which should be set
before the dual rates and exponential, Trim
(TRIM), which fine-tunes adjustments to
what the modeler has input with the levers
on the front of the transmitter and stores the
trim values in its memory, and Sub-Trims
(STRM).
For more experienced modelers, there are
programmable mixes to help correct
unwanted flight tendencies as well as the
ability to select which type of a wing he or

configuration), and V-tail mixing. The
settings are not available in “normal” mode.
There are also throttle-curve settings for
internal combustion engines, as well as
pitch-curve settings for variable-pitch
propellers on aircraft.
The Futaba 6J is also applicable to
helicopter modes and functions, including
throttle hold, idle up, gyro sensitivity, and
pitch to rudder mixing (REVO). All of the
helicopter programming is separated from
the airplane programming in the instruction
manual. This is indicated in the beginning
of each section with the words ACRO or
HELI.
When all of the function settings are in
place, the 6J can be set up for the training
function.
There are three training modes: normal
(controlled by signals from the student’s
transmitter), function (controlled by signals
from the student’s transmitter using the
instructor’s settings), and off (the
instructor’s transmitter provides the input
for the channel).
Until it is set within the mode functions
of the transmitter, the trainer function
cannot be used and the trainer menu will
show “INH” for inhibited. It can switched
on by pressing the data input lever upward
for two seconds. There will be a beep.
Now that I’ve gotten the hang of it, I’ll
know exactly what I need to do for the next
airplane. This was a great radio to learn to
fly with. Who knows … I may need to learn
the heli settings as well! MA

The R2006GS S-FHSS receiver, shown connected to
throttle, elevator, and rudder controls, is on a diversity
antenna system, which maximizes the signal reception and
allows the modeler to fly trouble-free. It also adapts to the
transmission mode (S-FHSS or FHSS).
I could not link to or fly other airplanes or helicopters with my
transmitter if the aircraft were set up with FASST system
receivers.
Easy learning began with the instruction manual. I read it before
I took the system out of the box. From the beginning, I found the

throttle-cut, mode settings, and a total reset
are programmed here. The manual does a
good job of taking the modeler through each
step, numbering the steps, and providing
photos of each screen.
Selecting the aircraft type was slightly
confusing. At first I wasn’t sure (when the
model type was blinking) whether I needed to
press a button after using data input to select
the correct type. I expected it to stop blinking
once I selected the right type, but it didn’t.
The 6J has memory for 15 different
models, and additional models can be
assigned different channels. It can also name
each model in memory which is nice (choose
MODL for the model-select function).
By pressing “select” while in the MODL
menu, then using the data input button above
it, you can scroll through the alphabet and
numbers to designate a four-character name
for your model. When finished, hit the end
button.
Because my model is the Flutter-By I
named it “FRBY.” Creating a name similar
to that of the airplane makes it easy to
remember which aircraft is assigned to what
channel.
All data in the transmitter can also be
reset to factory settings if needed. This
comes in handy if the airplane crashes and is
no longer flyable, or you want a fresh start.
This setting is under the model reset (REST,
in the PARA menu). It only impacts and
resets the model that is on the screen, not all
in memory, so if you have 15 models only
that particular model is wiped out.
I knew I wanted to be in fail-safe mode
(everyone should do this for safety), and the
S-FHSS mode on the 6J offers fail-safe on
all channels, so models added in the future
will automatically be set to fail-safe.
Whether this mode or FHSS mode is chosen,
the compatible receiver adjusts accordingly
to the signals from the transmitter.
S-FHSS also offers a battery fail-safe
mode that is activated as a factory default. If
the battery voltage drops below 3.8 volts, it
moves the throttle servo to a predetermined
position.
The throttle-cut is a nice factory setting
for internal combustion engines, but can be
switched to ESC for electrics. The throttlecut
button is on the front of the transmitter.
When used and set, it beeps and flashes the
word “MIX” on the LCD screen. The
throttle does not accelerate or decelerate
when it is set. To turn it off, press the button
again. This is a great accessory, especially
for a new modeler.
In terms of dual rates and exponential
(expo), the definitions in the manual are
vague. Beginners may need to do some
online research for better understanding. The
manual states that dual rates are: “… the
ability to change the travel distance of a
servo or servos, affecting the overall travel
of the servo(s). Thus, decreasing the
percentage value for a given servo will
reduce the travel amount of the channel
respectively.”
In other words, dual rates change how far
the control surfaces can move with respect
to the stick movements on the radio. A
lower percentage value for dual rates is
better for the beginner, producing gentler
movement. (Overcontrol is common with
someone just learning to fly.) A higher rate
will allow the flier to do rolls and flips and
be more aggressive.
Exponential “affects the travel of the
servos around their center in relationship to
stick movement.” It increases or decreases
the sensitivity around the central or neutral
stick position. Futaba transmitters use
negative expo (the opposite of other
transmitter brands), so make sure you are
going the right way. Positive expo increases
sensitivity and negative reduces it, making
the movements softer and milder at a lower
percentage. Too much (positive) can make
the airplane react too fast, while less expo
(negative) makes it easier to control.
The easiest way to test what feels right to
you, and the functions of dual rates and
exponential, is to have your model setting on
the table or workbench and play with the
controls. See how different settings on the
transmitter affect the movements, especially
in high and low rates.
Other function menus include End Point
Adjustment (EPA), which should be set
before the dual rates and exponential, Trim
(TRIM), which fine-tunes adjustments to
what the modeler has input with the levers
on the front of the transmitter and stores the
trim values in its memory, and Sub-Trims
(STRM).
For more experienced modelers, there are
programmable mixes to help correct
unwanted flight tendencies as well as the
ability to select which type of a wing he or

of each section with the words ACRO or
HELI.

I DECIDED to review the Futaba 6J Radio System from the
perspective of a beginner, because I am one, and for others who
are looking for a reliable, easy-to-learn transmitter.
Right out of the box, the biggest difference with this
radio system is that it has Frequency-Hopping Spread
Spectrum (FHSS) technology instead of Futaba Advanced
Spread Spectrum Technology (FASST). FHSS transmits on
a narrow-band frequency, but changes the frequency of
transmission hundreds of times a second. The receiver has
to know the frequency-changing pattern to switch to
different frequencies in the same order and time frame as
the transmitter.
FASST hops to different frequencies every 2 milliseconds
and is not compatible with FHSSS technology.
The Futaba 6J
Radio System is
an asset to any
type of aircraft
flown whether
the pi lot is a
beginner or more
advanced.

The control sticks can be adjusted to
make it comfortable for the modeler to
hold and operate the transmitter. The
stick tip can be turned counterclockwise,
while holding the locking piece, to
lengthen or shorten the stick.

The R2006GS S-FHSS receiver, shown connected to
throttle, elevator, and rudder controls, is on a diversity
antenna system, which maximizes the signal reception and
allows the modeler to fly trouble-free. It also adapts to the
transmission mode (S-FHSS or FHSS).
I could not link to or fly other airplanes or helicopters with my
transmitter if the aircraft were set up with FASST system
receivers.
Easy learning began with the instruction manual. I read it before
I took the system out of the box. From the beginning, I found the
instructions handy. I thoroughly reviewed the clear and concise
material. When I was ready to go through the settings on the
radio, I reread each section step by step.
One of the first sections in the manual is a glossary, which is
helpful for someone who is unfamiliar with some of these terms.
They were in logical order, but I would have preferred for them
to be in alphabetical order for quicker access, with possibly a
note at the end of each definition with other relevant terms.
I never felt lost in the terminology and there were plenty of
photos, as well as illustrations, for each section. The instructions
began with an introduction to the transmitter controls, then
moved on to radio and receiver installation, range-checking the
radio, the linking procedure, what each alarm and warning bell
meant, and then finished with programming the system. Although
some of the initial steps were already completed at the factory, it
was nice to have the instructions.
I was ready to program the radio and pick
up and handle the transmitter. The first thing
I noticed was that there was no antenna. The
6J transmitter antenna is internal—a nice
upgrade. I felt at ease knowing this radio
would have full range without the
bothersome antenna.
The weight of the transmitter was a
concern, and I wondered how well I could
handle it and if I would need to purchase a
transmitter tray. I was surprised at how
lightweight and comfortable it was to hold.
The four AA batteries hardly added any
weight. A five-cell NiCd/NiMH pack could
also be used. The angle of the transmitter
made it easy to grip.
I was also worried about being able to
control the sticks, but the 6J fit nicely in my
small hands. Although I’m still deciding
whether to pinch or thumb-fly, I felt
comfortable trying both ways. The length
can be adjusted, and the instructions are in
the back of the manual.
The airplane I planned to fly with my
transmitter is called a Flutter-By. It only has
rudder, elevator, and throttle controls, plus
optional LED lights for night-flying. The
designer labeled each servo wire, making the
connection easier to figure out.
The manual included directions for
setting up and connecting the receiver and
“relinking” (the receiver is linked at the
factory). When I attempted to link, the
receiver flashed a red light, meaning there
was no signal. After unplugging the battery
and plugging it back in, the receiver light
once again turned green and stopped
flashing.
I also did a range-check with the 6J’s
special power-down mode. It’s a great
opportunity (especially when you’re flying a
model for the first time) to make sure the
equipment is properly working.
To complete the range-check, follow the
instructions in the manual: walk 30 to 50
paces from the model while simultaneously
operating the controls on the transmitter, and
have an assistant stand by the model to let
you know that everything is working as it
should.
Walk back and start the engine (if it is
internal combustion, make sure the throttle
stick is all the way down), and repeat the
steps. Run the airplane up at various throttle
speeds, but remember not to try to fly the
model in this mode, although it does revert
back to full-range mode after 90 seconds.
The blue light on the front of the model
will blink and beep when you begin the
range-check. The word “down” also blinks
on the LED screen, so there is no way to
mistake that the transmitter is in this mode.
Now is when the controls and program
functions come into play. The instruction
manual explains each program’s function
and the purpose of each button on the front
of the transmitter.
The buttons on the front of the transmitter
are simple, and the faceplate is uncluttered.
To the left of the LCD screen, the top button
is the mode key. This button is used to view,
select, and change the different program
functions and settings on the 6J.
Press and hold this button for one second,
then scroll up or down through the different
settings, using it and the bottom left button,
which is the “end” key. (There are arrows to
the left of both keys that indicate these
buttons can be used for scrolling through
different settings.) The transmitter beeps
when selecting from screen to screen.
To the right of the LCD screen is the data
input key. Use this button to change the
values in each programming mode. Use the
bottom key on the right side (the select key)
to set the function/mode.
The Parameters (PARA) menu is the first
one that I set up, using the mode button for
access. The aircraft type (airplane or a
helicopter) model selection, and name,
throttle-cut, mode settings, and a total reset
are programmed here. The manual does a
good job of taking the modeler through each
step, numbering the steps, and providing
photos of each screen.
Selecting the aircraft type was slightly
confusing. At first I wasn’t sure (when the
model type was blinking) whether I needed to
press a button after using data input to select
the correct type. I expected it to stop blinking
once I selected the right type, but it didn’t.
The 6J has memory for 15 different
models, and additional models can be
assigned different channels. It can also name
each model in memory which is nice (choose
MODL for the model-select function).
By pressing “select” while in the MODL
menu, then using the data input button above
it, you can scroll through the alphabet and
numbers to designate a four-character name
for your model. When finished, hit the end
button.
Because my model is the Flutter-By I
named it “FRBY.” Creating a name similar
to that of the airplane makes it easy to
remember which aircraft is assigned to what
channel.
All data in the transmitter can also be
reset to factory settings if needed. This
comes in handy if the airplane crashes and is
no longer flyable, or you want a fresh start.
This setting is under the model reset (REST,
in the PARA menu). It only impacts and
resets the model that is on the screen, not all
in memory, so if you have 15 models only
that particular model is wiped out.
I knew I wanted to be in fail-safe mode
(everyone should do this for safety), and the
S-FHSS mode on the 6J offers fail-safe on
all channels, so models added in the future
will automatically be set to fail-safe.
Whether this mode or FHSS mode is chosen,
the compatible receiver adjusts accordingly
to the signals from the transmitter.
S-FHSS also offers a battery fail-safe
mode that is activated as a factory default. If
the battery voltage drops below 3.8 volts, it
moves the throttle servo to a predetermined
position.
The throttle-cut is a nice factory setting
for internal combustion engines, but can be
switched to ESC for electrics. The throttlecut
button is on the front of the transmitter.
When used and set, it beeps and flashes the
word “MIX” on the LCD screen. The
throttle does not accelerate or decelerate
when it is set. To turn it off, press the button
again. This is a great accessory, especially
for a new modeler.
In terms of dual rates and exponential
(expo), the definitions in the manual are
vague. Beginners may need to do some
online research for better understanding. The
manual states that dual rates are: “… the
ability to change the travel distance of a
servo or servos, affecting the overall travel
of the servo(s). Thus, decreasing the
percentage value for a given servo will
reduce the travel amount of the channel
respectively.”
In other words, dual rates change how far
the control surfaces can move with respect
to the stick movements on the radio. A
lower percentage value for dual rates is
better for the beginner, producing gentler
movement. (Overcontrol is common with
someone just learning to fly.) A higher rate
will allow the flier to do rolls and flips and
be more aggressive.
Exponential “affects the travel of the
servos around their center in relationship to
stick movement.” It increases or decreases
the sensitivity around the central or neutral
stick position. Futaba transmitters use
negative expo (the opposite of other
transmitter brands), so make sure you are
going the right way. Positive expo increases
sensitivity and negative reduces it, making
the movements softer and milder at a lower
percentage. Too much (positive) can make
the airplane react too fast, while less expo
(negative) makes it easier to control.
The easiest way to test what feels right to
you, and the functions of dual rates and
exponential, is to have your model setting on
the table or workbench and play with the
controls. See how different settings on the
transmitter affect the movements, especially
in high and low rates.
Other function menus include End Point
Adjustment (EPA), which should be set
before the dual rates and exponential, Trim
(TRIM), which fine-tunes adjustments to
what the modeler has input with the levers
on the front of the transmitter and stores the
trim values in its memory, and Sub-Trims
(STRM).

The R2006GS S-FHSS receiver, shown connected to
throttle, elevator, and rudder controls, is on a diversity
antenna system, which maximizes the signal reception and
allows the modeler to fly trouble-free. It also adapts to the
transmission mode (S-FHSS or FHSS).
I could not link to or fly other airplanes or helicopters with my
transmitter if the aircraft were set up with FASST system
receivers.
Easy learning began with the instruction manual. I read it before
I took the system out of the box. From the beginning, I found the
instructions handy. I thoroughly reviewed the clear and concise
material. When I was ready to go through the settings on the
radio, I reread each section step by step.
One of the first sections in the manual is a glossary, which is
helpful for someone who is unfamiliar with some of these terms.
They were in logical order, but I would have preferred for them
to be in alphabetical order for quicker access, with possibly a
note at the end of each definition with other relevant terms.
I never felt lost in the terminology and there were plenty of
photos, as well as illustrations, for each section. The instructions
began with an introduction to the transmitter controls, then
moved on to radio and receiver installation, range-checking the
radio, the linking procedure, what each alarm and warning bell
meant, and then finished with programming the system. Although
some of the initial steps were already completed at the factory, it
was nice to have the instructions.
I was ready to program the radio and pick
up and handle the transmitter. The first thing
I noticed was that there was no antenna. The
6J transmitter antenna is internal—a nice
upgrade. I felt at ease knowing this radio
would have full range without the
bothersome antenna.
The weight of the transmitter was a
concern, and I wondered how well I could
handle it and if I would need to purchase a
transmitter tray. I was surprised at how
lightweight and comfortable it was to hold.
The four AA batteries hardly added any
weight. A five-cell NiCd/NiMH pack could
also be used. The angle of the transmitter
made it easy to grip.
I was also worried about being able to
control the sticks, but the 6J fit nicely in my
small hands. Although I’m still deciding
whether to pinch or thumb-fly, I felt
comfortable trying both ways. The length
can be adjusted, and the instructions are in
the back of the manual.
The airplane I planned to fly with my
transmitter is called a Flutter-By. It only has
rudder, elevator, and throttle controls, plus
optional LED lights for night-flying. The
designer labeled each servo wire, making the
connection easier to figure out.
The manual included directions for
setting up and connecting the receiver and
“relinking” (the receiver is linked at the
factory). When I attempted to link, the
receiver flashed a red light, meaning there
was no signal. After unplugging the battery
and plugging it back in, the receiver light
once again turned green and stopped
flashing.
I also did a range-check with the 6J’s
special power-down mode. It’s a great
opportunity (especially when you’re flying a
model for the first time) to make sure the
equipment is properly working.
To complete the range-check, follow the
instructions in the manual: walk 30 to 50
paces from the model while simultaneously
operating the controls on the transmitter, and
have an assistant stand by the model to let
you know that everything is working as it
should.
Walk back and start the engine (if it is
internal combustion, make sure the throttle
stick is all the way down), and repeat the
steps. Run the airplane up at various throttle
speeds, but remember not to try to fly the
model in this mode, although it does revert
back to full-range mode after 90 seconds.
The blue light on the front of the model
will blink and beep when you begin the
range-check. The word “down” also blinks
on the LED screen, so there is no way to
mistake that the transmitter is in this mode.
Now is when the controls and program
functions come into play. The instruction
manual explains each program’s function
and the purpose of each button on the front
of the transmitter.
The buttons on the front of the transmitter
are simple, and the faceplate is uncluttered.
To the left of the LCD screen, the top button
is the mode key. This button is used to view,
select, and change the different program
functions and settings on the 6J.
Press and hold this button for one second,
then scroll up or down through the different
settings, using it and the bottom left button,
which is the “end” key. (There are arrows to
the left of both keys that indicate these
buttons can be used for scrolling through
different settings.) The transmitter beeps
when selecting from screen to screen.
To the right of the LCD screen is the data
input key. Use this button to change the
values in each programming mode. Use the
bottom key on the right side (the select key)
to set the function/mode.
The Parameters (PARA) menu is the first
one that I set up, using the mode button for
access. The aircraft type (airplane or a
helicopter) model selection, and name,
throttle-cut, mode settings, and a total reset
are programmed here. The manual does a
good job of taking the modeler through each
step, numbering the steps, and providing
photos of each screen.
Selecting the aircraft type was slightly
confusing. At first I wasn’t sure (when the
model type was blinking) whether I needed to
press a button after using data input to select
the correct type. I expected it to stop blinking
once I selected the right type, but it didn’t.
The 6J has memory for 15 different
models, and additional models can be
assigned different channels. It can also name
each model in memory which is nice (choose
MODL for the model-select function).
By pressing “select” while in the MODL
menu, then using the data input button above
it, you can scroll through the alphabet and
numbers to designate a four-character name
for your model. When finished, hit the end
button.
Because my model is the Flutter-By I
named it “FRBY.” Creating a name similar
to that of the airplane makes it easy to
remember which aircraft is assigned to what
channel.
All data in the transmitter can also be
reset to factory settings if needed. This
comes in handy if the airplane crashes and is
no longer flyable, or you want a fresh start.
This setting is under the model reset (REST,
in the PARA menu). It only impacts and
resets the model that is on the screen, not all
in memory, so if you have 15 models only
that particular model is wiped out.
I knew I wanted to be in fail-safe mode
(everyone should do this for safety), and the
S-FHSS mode on the 6J offers fail-safe on
all channels, so models added in the future
will automatically be set to fail-safe.
Whether this mode or FHSS mode is chosen,
the compatible receiver adjusts accordingly
to the signals from the transmitter.
S-FHSS also offers a battery fail-safe
mode that is activated as a factory default. If
the battery voltage drops below 3.8 volts, it
moves the throttle servo to a predetermined
position.
The throttle-cut is a nice factory setting
for internal combustion engines, but can be
switched to ESC for electrics. The throttlecut
button is on the front of the transmitter.
When used and set, it beeps and flashes the
word “MIX” on the LCD screen. The
throttle does not accelerate or decelerate
when it is set. To turn it off, press the button
again. This is a great accessory, especially
for a new modeler.
In terms of dual rates and exponential
(expo), the definitions in the manual are
vague. Beginners may need to do some
online research for better understanding. The
manual states that dual rates are: “… the
ability to change the travel distance of a
servo or servos, affecting the overall travel
of the servo(s). Thus, decreasing the
percentage value for a given servo will
reduce the travel amount of the channel
respectively.”
In other words, dual rates change how far
the control surfaces can move with respect
to the stick movements on the radio. A
lower percentage value for dual rates is
better for the beginner, producing gentler
movement. (Overcontrol is common with
someone just learning to fly.) A higher rate
will allow the flier to do rolls and flips and
be more aggressive.
Exponential “affects the travel of the
servos around their center in relationship to
stick movement.” It increases or decreases
the sensitivity around the central or neutral
stick position. Futaba transmitters use
negative expo (the opposite of other
transmitter brands), so make sure you are
going the right way. Positive expo increases
sensitivity and negative reduces it, making
the movements softer and milder at a lower
percentage. Too much (positive) can make
the airplane react too fast, while less expo
(negative) makes it easier to control.
The easiest way to test what feels right to
you, and the functions of dual rates and
exponential, is to have your model setting on
the table or workbench and play with the
controls. See how different settings on the
transmitter affect the movements, especially
in high and low rates.
Other function menus include End Point
Adjustment (EPA), which should be set
before the dual rates and exponential, Trim
(TRIM), which fine-tunes adjustments to
what the modeler has input with the levers
on the front of the transmitter and stores the
trim values in its memory, and Sub-Trims
(STRM).
For more experienced modelers, there are
programmable mixes to help correct
unwanted flight tendencies as well as the
ability to select which type of a wing he or

configuration), and V-tail mixing. The
settings are not available in “normal” mode.
There are also throttle-curve settings for
internal combustion engines, as well as
pitch-curve settings for variable-pitch
propellers on aircraft.
The Futaba 6J is also applicable to
helicopter modes and functions, including
throttle hold, idle up, gyro sensitivity, and
pitch to rudder mixing (REVO). All of the
helicopter programming is separated from
the airplane programming in the instruction
manual. This is indicated in the beginning
of each section with the words ACRO or
HELI.
When all of the function settings are in
place, the 6J can be set up for the training
function.
There are three training modes: normal
(controlled by signals from the student’s
transmitter), function (controlled by signals
from the student’s transmitter using the
instructor’s settings), and off (the
instructor’s transmitter provides the input
for the channel).
Until it is set within the mode functions
of the transmitter, the trainer function
cannot be used and the trainer menu will
show “INH” for inhibited. It can switched
on by pressing the data input lever upward
for two seconds. There will be a beep.
Now that I’ve gotten the hang of it, I’ll
know exactly what I need to do for the next
airplane. This was a great radio to learn to
fly with. Who knows … I may need to learn
the heli settings as well! MA

I DECIDED to review the Futaba 6J Radio System from the
perspective of a beginner, because I am one, and for others who
are looking for a reliable, easy-to-learn transmitter.
Right out of the box, the biggest difference with this
radio system is that it has Frequency-Hopping Spread
Spectrum (FHSS) technology instead of Futaba Advanced
Spread Spectrum Technology (FASST). FHSS transmits on
a narrow-band frequency, but changes the frequency of
transmission hundreds of times a second. The receiver has
to know the frequency-changing pattern to switch to
different frequencies in the same order and time frame as
the transmitter.
FASST hops to different frequencies every 2 milliseconds
and is not compatible with FHSSS technology.
The Futaba 6J
Radio System is
an asset to any
type of aircraft
flown whether
the pi lot is a
beginner or more
advanced.

while holding the locking piece, to
lengthen or shorten the stick.

throttle, elevator, and rudder controls, is on a diversity

allows the modeler to fly trouble-free. It also adapts to the
transmission mode (S-FHSS or FHSS).
I could not link to or fly other airplanes or helicopters with my
transmitter if the aircraft were set up with FASST system
receivers.
Easy learning began with the instruction manual. I read it before
I took the system out of the box. From the beginning, I found the
instructions handy. I thoroughly reviewed the clear and concise
material. When I was ready to go through the settings on the
radio, I reread each section step by step.
One of the first sections in the manual is a glossary, which is
helpful for someone who is unfamiliar with some of these terms.
They were in logical order, but I would have preferred for them
to be in alphabetical order for quicker access, with possibly a
note at the end of each definition with other relevant terms.
I never felt lost in the terminology and there were plenty of
photos, as well as illustrations, for each section. The instructions
began with an introduction to the transmitter controls, then
moved on to radio and receiver installation, range-checking the
radio, the linking procedure, what each alarm and warning bell
meant, and then finished with programming the system. Although
some of the initial steps were already completed at the factory, it
was nice to have the instructions.
I was ready to program the radio and pick
up and handle the transmitter. The first thing
I noticed was that there was no antenna. The
6J transmitter antenna is internal—a nice
upgrade. I felt at ease knowing this radio
would have full range without the
bothersome antenna.
The weight of the transmitter was a

The four AA batteries hardly added any

also be used. The angle of the transmitter
made it easy to grip.
I was also worried about being able to

small hands. Although I’m still deciding
whether to pinch or thumb-fly, I felt
comfortable trying both ways. The length
can be adjusted, and the instructions are in
the back of the manual.
The airplane I planned to fly with my
transmitter is called a Flutter-By. It only has
rudder, elevator, and throttle controls, plus
optional LED lights for night-flying. The
designer labeled each servo wire, making the
connection easier to figure out.
The manual included directions for
setting up and connecting the receiver and
“relinking” (the receiver is linked at the
factory). When I attempted to link, the
receiver flashed a red light, meaning there
was no signal. After unplugging the battery
and plugging it back in, the receiver light
once again turned green and stopped
flashing.
I also did a range-check with the 6J’s
special power-down mode. It’s a great
opportunity (especially when you’re flying a
model for the first time) to make sure the
equipment is properly working.
To complete the range-check, follow the
instructions in the manual: walk 30 to 50
paces from the model while simultaneously
operating the controls on the transmitter, and
have an assistant stand by the model to let
you know that everything is working as it
should.
Walk back and start the engine (if it is
internal combustion, make sure the throttle
stick is all the way down), and repeat the
steps. Run the airplane up at various throttle
speeds, but remember not to try to fly the
model in this mode, although it does revert
back to full-range mode after 90 seconds.
The blue light on the front of the model
will blink and beep when you begin the
range-check. The word “down” also blinks
on the LED screen, so there is no way to
mistake that the transmitter is in this mode.
Now is when the controls and program
functions come into play. The instruction
manual explains each program’s function
and the purpose of each button on the front
of the transmitter.
The buttons on the front of the transmitter
are simple, and the faceplate is uncluttered.
To the left of the LCD screen, the top button
is the mode key. This button is used to view,
select, and change the different program
functions and settings on the 6J.
Press and hold this button for one second,
then scroll up or down through the different
settings, using it and the bottom left button,
which is the “end” key. (There are arrows to
the left of both keys that indicate these
buttons can be used for scrolling through
different settings.) The transmitter beeps
when selecting from screen to screen.
To the right of the LCD screen is the data
input key. Use this button to change the
values in each programming mode. Use the
bottom key on the right side (the select key)
to set the function/mode.
The Parameters (PARA) menu is the first
one that I set up, using the mode button for
access. The aircraft type (airplane or a
helicopter) model selection, and name,
throttle-cut, mode settings, and a total reset
are programmed here. The manual does a
good job of taking the modeler through each
step, numbering the steps, and providing
photos of each screen.
Selecting the aircraft type was slightly
confusing. At first I wasn’t sure (when the
model type was blinking) whether I needed to
press a button after using data input to select
the correct type. I expected it to stop blinking
once I selected the right type, but it didn’t.
The 6J has memory for 15 different
models, and additional models can be
assigned different channels. It can also name
each model in memory which is nice (choose
MODL for the model-select function).
By pressing “select” while in the MODL
menu, then using the data input button above
it, you can scroll through the alphabet and
numbers to designate a four-character name
for your model. When finished, hit the end
button.
Because my model is the Flutter-By I
named it “FRBY.” Creating a name similar
to that of the airplane makes it easy to
remember which aircraft is assigned to what
channel.
All data in the transmitter can also be
reset to factory settings if needed. This
comes in handy if the airplane crashes and is
no longer flyable, or you want a fresh start.
This setting is under the model reset (REST,
in the PARA menu). It only impacts and
resets the model that is on the screen, not all
in memory, so if you have 15 models only
that particular model is wiped out.
I knew I wanted to be in fail-safe mode
(everyone should do this for safety), and the
S-FHSS mode on the 6J offers fail-safe on
all channels, so models added in the future
will automatically be set to fail-safe.
Whether this mode or FHSS mode is chosen,
the compatible receiver adjusts accordingly
to the signals from the transmitter.
S-FHSS also offers a battery fail-safe
mode that is activated as a factory default. If
the battery voltage drops below 3.8 volts, it
moves the throttle servo to a predetermined
position.
The throttle-cut is a nice factory setting
for internal combustion engines, but can be
switched to ESC for electrics. The throttlecut
button is on the front of the transmitter.
When used and set, it beeps and flashes the
word “MIX” on the LCD screen. The
throttle does not accelerate or decelerate
when it is set. To turn it off, press the button
again. This is a great accessory, especially
for a new modeler.
In terms of dual rates and exponential
(expo), the definitions in the manual are
vague. Beginners may need to do some
online research for better understanding. The
manual states that dual rates are: “… the
ability to change the travel distance of a
servo or servos, affecting the overall travel
of the servo(s). Thus, decreasing the
percentage value for a given servo will
reduce the travel amount of the channel
respectively.”
In other words, dual rates change how far
the control surfaces can move with respect
to the stick movements on the radio. A
lower percentage value for dual rates is
better for the beginner, producing gentler
movement. (Overcontrol is common with
someone just learning to fly.) A higher rate
will allow the flier to do rolls and flips and
be more aggressive.
Exponential “affects the travel of the
servos around their center in relationship to
stick movement.” It increases or decreases
the sensitivity around the central or neutral
stick position. Futaba transmitters use
negative expo (the opposite of other
transmitter brands), so make sure you are
going the right way. Positive expo increases
sensitivity and negative reduces it, making
the movements softer and milder at a lower
percentage. Too much (positive) can make
the airplane react too fast, while less expo
(negative) makes it easier to control.
The easiest way to test what feels right to
you, and the functions of dual rates and
exponential, is to have your model setting on
the table or workbench and play with the
controls. See how different settings on the
transmitter affect the movements, especially
in high and low rates.
Other function menus include End Point
Adjustment (EPA), which should be set
before the dual rates and exponential, Trim
(TRIM), which fine-tunes adjustments to
what the modeler has input with the levers
on the front of the transmitter and stores the
trim values in its memory, and Sub-Trims
(STRM).
For more experienced modelers, there are
programmable mixes to help correct
unwanted flight tendencies as well as the
ability to select which type of a wing he or

she is using beyond the normal flaperon,
elevon (such as a Delta-wing
configuration), and V-tail mixing. The
settings are not available in “normal” mode.
There are also throttle-curve settings for
internal combustion engines, as well as
pitch-curve settings for variable-pitch
propellers on aircraft.
The Futaba 6J is also applicable to
helicopter modes and functions, including
throttle hold, idle up, gyro sensitivity, and
pitch to rudder mixing (REVO). All of the
helicopter programming is separated from
the airplane programming in the instruction
manual. This is indicated in the beginning
of each section with the words ACRO or
HELI.
When all of the function settings are in
place, the 6J can be set up for the training
function.
There are three training modes: normal
(controlled by signals from the student’s
transmitter), function (controlled by signals
from the student’s transmitter using the
instructor’s settings), and off (the
instructor’s transmitter provides the input
for the channel).
Until it is set within the mode functions
of the transmitter, the trainer function
cannot be used and the trainer menu will
show “INH” for inhibited. It can switched
on by pressing the data input lever upward
for two seconds. There will be a beep.
Now that I’ve gotten the hang of it, I’ll
know exactly what I need to do for the next
airplane. This was a great radio to learn to
fly with. Who knows … I may need to learn
the heli settings as well! MA
