Primitive camping is available on-site, and
there are plenty of hotels in the area. The event
schedule is posted on the Jet World Masters
website, as is lodging and travel information, a
listing of local activities, and almost about any
other information you might want.
Support for this event is coming along
well, both with volunteers and sponsors. It
takes many people and much funding to put on
competitions such as this. Roger Shipley and
Dewey Davenport have taken on organizing
and running the event, and Lance Campbell is
the CD.
Roger and Dewey are past Jet World
Masters competitors, and check out Lance’s
SR-71 on his website. What a craftsman!
Additional volunteers include David
Brawley, who is organizing demonstration
flying, and Lewis Patton, a US team pilot and
Kentucky Jets CD who is stepping up to CD
the open flying. Many other volunteers are
serving in numerous positions to make the Jet
World Masters happen.
Check out the event website, and thanks to
all who are helping to make this Jet World
Masters one of which we can be proud. It is an
honor to be part of this international event.
RC Universe has really been a help, and
Ken Isaac, the RC Universe forum manager,

will make photographs available. Just make
sure to give RC Universe credit; that is a
generous offer.
I hope to see you there; stop by and say hi!

Sport jets don’t get much bigger than a Tomahawk Design Futura.
With looks you probably either love or hate, it is an excellent-flying
precision aerobatic sport jet—especially if speed isn’t your thing.
David Shulman owns and flies this Pirotti Tuono—another large
sport jet for the turbine enthusiast. David is a showman who
gets all the performance he can from this great-flying model.

THIS PROMISES TO be a great summer for
jet flying. One of the highlights will be the Jet
World Masters contest that the International
Jet Model Committee (IMJC) is hosting in
Dayton, Ohio.
As stated in its constitution, the IMJC was
established to bring jet modelers together to
“bring jet scale competition to an
internationally accepted class.” It has done this
by holding competitions throughout the world,
and now in North America.
The contest will be held at the National
Museum of the United States Air Force during
the course of two weeks: July 24-August 6.
This promises to be one of the largest World
Jet Masters yet, featuring some of the best
Scale jets and the best Scale jet modelers from
around the world. As I am writing this, more
than 80 pilots from 20 countries have
preregistered.
Time will be allotted not only for
competition flying at this event, but also for
practice, demonstration flights, and even open
flying. So bring your jets and fly at one of the

part of this prestigious event.
The AMA’s Large Model Aircraft Program
has undergone some changes. Check out
Document 520-A on the Academy’s website
to learn about them. If you already fly an
experimental-class model, this will be a
welcome set of new regulations.
Large Model Aircraft (LMA) are now
divided into two basic weight categories.
LMA-1 is for models weighing 55.0-77.2
pounds, and LMA-2 is for those weighing
77.3-125.0 pounds. For turbine-powered
aircraft, the classification LTMA-1 is for
55.0-77.2 pounds and LTMA-2 is for 77.3-
100.0 pounds.
The permit-to-fly process and annual
recertification for LTMA-1 and LMA-1 are
now simplified, based on the success of the
existing program, and the LTMA-2 and
LMA-2 permit-to-fly process and
recertification remain similar to the old
experimental class.
What does this mean? The LTMA-1 rules
require two witnesses for the permit-to-fly
certification; they can be a CD, a Leader
Member, or a Large Model Aircraft Inspector
(LMAI). That class does not require an LMAI
to be the sole witness of a flight to sign off on
the permit.
If you have an interest in models this big
or are CD of an event in which large models
might participate, take the time to check out
this document.
As I write this, I have just returned home
from Florida Jets. The venue was Paradise
Field in Lakeland.
It’s a grass site, and that was controversial
before the event, but all turned out well. We
learned from this experience that not all jets
are set up for grass-field operations.
I took my new Der Jet Model de
Havilland Vampire, which is good for
grass-field flying, but sand got to my new
retract units. There was not enough

clearance between the machined surfaces
for the grit to fit, causing gears to stick.
The retract mechanism slots and then the
scissors-type nose gear’s smooth motion was
compromised. I had none of those problems
on the bench or at my paved field back home.
Paradise Field was not as flat as a golf
green; it had rollers that tested the shock struts
on our jets, and only a few models had
problems. The reasons why were obvious
with most of them.
Scale F-100s and similar aircraft were not
designed for rough grass operation; their tires
are too small for their weight. But Jack Diaz
must have had more than a dozen flights in
and out of the field with his F-100, so it
wasn’t that bad.
Few of the large-scale jets had issues.
Heck, my Vampire, with its 35-pound takeoff
weight and only a 20-pound-thrust Jet Central
Rabbit turbine, got a clean takeoff every time.
I’ll be back to Paradise Field for future
events.
Even the smaller BVM BobCats,
composite Habus, and JetCat P20-powered
models had no issues with the grass; their
landing gear setups worked well. I saw only
two or three electric-powered and small
aircraft that had difficulty getting off of the
ground, and their problems stemmed from
power issues and small tires.
Big scale and sport models ruled at
Florida Jets, and the new trend of large sport
jets designed for aerobatics was evident. The
BVM Ultra Bandit has been around for a
while, and its sweet flying characteristics
combined with its size made it one of the
most popular turbine models on the field.
Tomahawk Design has come out with the
Futura—a big, slow-flying design that was
made specifically for precision aerobatics. It
spans 100 inches, is approximately 105
inches long, and has the largest, tallest
fuselage I have ever seen. This jet is meant to
knife edge.
Andy Kane flew a borrowed Futura as if it
were his all week during Florida Jets. He
demonstrated the aerobatic capabilities of this
unusual design.
The goal of this model is constant-speed
aerobatics, so drag is its friend—and so is the
light weight for its size. The typical empty
weight of the Futura is roughly 42 pounds,
and the one that Andy flew had plenty of
power with its awesome Jet Central
Mammoth turbine.
The unusual thing about this jet is the
intakes; it has no ductwork. The designer wants
the drag to reduce the top speed, reduce
acceleration and speed on down-lines, and
work toward the constant-airspeed aerobatics.
That setup works well of the Futura. Don’t
expect to run with an Ultra Bandit on the top
end, but it makes airspeed control in the box
easier with all that drag. It’s a different type of
airplane for a different style of flying.
David Shulman flew a big sport jet from
Pirotti called the “Tuono.” It had a wingspan of
93 inches and an overall length of 96 inches.
The model was set up for David’s
aggressive flying. It went fast, and it could be
flown hard and then slowed and cruised
through an aerobatic routine at speeds rivaling
any International Miniature Aerobatic Club
model—but with the sound and precision of a
jet.
David put on quite an aerobatic show,
flying the Tuono through its entire speed range.
He performed high-speed rolls, knife edge on
the deck, and slow flight, demonstrating how
sweet this aircraft is.
This jet has a great deal of wing area for its
size and an unusually large stabilizer that was
designed for smooth, precision flying at all
speeds. It works well.
The manufacturer claims that with the right
turbine setup, the Tuono can be kept as light as
33 pounds. That’s impressive for a model this
size.
I’ll finish with a shot of Bob Violett’s
Skymaster A-4 that was painted to match the
full-scale A-4 he flew back in the day. It was
neat to see this model sitting out in front of the
BVM tent at Florida Jets.
I think this might become Bob’s favorite
jet. I’ll bet it’s hard for him to decide,
considering the selection of models and power
systems on his product shelf. MA
