Twin winter Old-Timer (OT)
contests are held each year in
mid-January. Both contests are
in warmer climates at opposite sides
of the country.
The relatively new Eastern event
was in Dade City, Florida. Barbara
Mulholland is a skilled OT RC  ier
who helps with the contest. She sent
this note about the Florida event:
“This was no doubt the best one so
far; three sunny days with reasonable
temperatures, but at times, annoying
winds. There were 25 contestants from
eight states and Canada—the most
we’ve ever had.
“We feature all the SAM [Society of
Antique Modelers] RC ignition, glow,
and electric events. Tom Boice helped
provide Winter-Fly coffee cups in
memory of his father. These cups were
given to each of the contestants and
were a big hit.”
In the West, I attended the 2012
Southwest Regionals (SWR), held in
Eloy, Arizona. The SWR was in its 67th
year. Great weather was enjoyed at this
end as well. It’s a much bigger contest
because it includes OT RC, but adds
OT FF, plus modern AMA FF, FAI, and
Nostalgia events. If you live in snow
country, why not plan to attend one of
these events next January?
Model Visibility
Model visibility at altitude during the
SWR was the best I’ve seen anywhere.
There was a thin, high overcast that
backlit any color scheme and made it
stand out as a silhouette.
Usually, no single color scheme works
best for all lighting conditions. Black,
or other dark colors work well against
white clouds, but fade out against a clear
blue sky. Lighter colors, such as white,
yellow, or orange seem to work well
against a clear sky, particularly if they’re
translucent.
It would be nice if contest managers
would arrange for a mix of blue sky and
white cumulus clouds so we could  y
under the area best suited for our color
scheme.
Obsolete Fuels Recalled
It was probably in the 1950s that
modelers began buying premixed fuels
instead of mixing their own. Answering
a question in the February 2012 column,
I mentioned that glow engines could be
run on gas and oil mix (no methanol)
if run fairly fast
and warm.
I received
this note from
George Lieb,
from Omaha,
Nebraska:
“Slow engines
also run  ne on
gas and oil—if
you add nitro
propane. I used
it in my K & B
.29 in my AMA
Team Racer in the 1950s. I don’t know if
or where it’s available anymore.
“We used 25% 70-weight motor oil,
Amoco high-test white gas, and about
20% nitro propane. It ran slower than
glow fuel, but way longer. We got about
half again as many laps as on glow fuel.”
Thanks, George. The idea was to run
more laps using the speci ed small tank
size, so you made fewer fuel stops. I
recall using nitro propane to give some
extra punch to gasoline, much the way
nitro methane does in glow fuel. But
that still didn’t allow gas to match the
power of glow fuel.
SAM competition rules today prohibit
using nitro in spark ignition engines, so
that rules out nitro propane and nitro
methane.
Another obsolete fuel ingredient
is nitro benzene. Even used in small
quantities, you could instantly recognize
it in a fuel mix because of its shoe
polish-like odor. I disposed of my
remaining supply many years ago after
learning of its highly carcinogenic
qualities.
Scale Documentation
Bob Banka sent a note regarding his
scale documentation service. He’s been
in business for 30 years and says he has
the world’s largest collection of photos
and three-views at 50,000-plus pages.
After looking at his website I certainly
believe it.
Bob covers more than I can begin to
address in any detail here.
Besides conventional models,
he includes Sailplanes, helicopters,
gyrocopters, engines, and some
weaponry. Most of the aircraft are old
designs. He has sales agents in half a
dozen countries outside the USA.
Prices for three-views start at $3 and
up. Bob’s Foto-Paks range from $6 to
more than $50 for some subjects. Spend
some time browsing his website. See
“Sources” for more information.
Walter Craig’s Engine Services
Engine services provided by Walter
Craig were announced in my February
2012 column. I mentioned that I had no
direct experience with his work, but had
heard no complaints.
Harvey Hartman of Waller, Texas,
used Walter’s services and sent a note
expressing his satisfaction. Here are
Harvey’s comments:
“I sent Mr. Walter Craig three vintage
ignition engines that I purchased on
eBay last year. Old ignition engines are
new territory for me and even though
I suspected they were in good shape, I
wanted an experienced eye to look them
over before I tried them.
“They were disassembled, cleaned, test
ran, and returned within two weeks. His
price was very affordable and he even
included a letter with recommendations
for prop sizes and fuel blend.
“Throughout the process, he kept
me informed via emails. I like that! I
now have three good-as-new vintage
sparkers ready to fly. I can thoroughly
recommend Mr. Craig’s services!”
Small Old-Timers
Small Old-Timer describes a model
category and a loosely organized group
of fun fliers spearheaded by SAM
secretary, Tommy Gray. This year they’ll
be flying once more as an added event at
the SAM Champs.
If outdoor winds are too high, the
group is looking at the possibilities of an
indoor venue. The models are scaleddown
versions of full-size SAM-eligible
designs. Wingspan is limited to no more
than 24 inches.
When I first heard of this movement
a few years ago, I envisioned a mix
of electrics and maybe .010- or
.020-powered FF and RC aircraft.
Practical matters seem to have narrowed
it down to electric-powered RC only,
but I doubt that you’d be thrown out of
an outdoor fun-fly event if you showed
up with a .010 “nitro”-powered aircraft.
Further information and the few
rules are posted on the SmallOldTimers
website, listed in “Sources.”
I had mentioned these small models
in the February 2012 issue of the SAM
26 newsletter, which I edit. Bob Aberle,
MA’s Technical Editor, saw a copy and
sent me a CD with data about the 10
small, electric Old-Timers he’d designed
and built for RC Micro World (RCMW)
magazine. John Worth started RCMW
several years ago, and after he passed
away, Roland Friestad revived it into an
electronic-only publication.

Bob Aberle is a prolific builder and
he didn’t stop after designing those 10
small OT models. He produces nearly
one a month, although most are not OT
designs. He’s made a comprehensive, 120-
page CD book filled with good technical
details about small, electric models. It’s
$10 postpaid for US delivery.
Here’s a quote from Bob in the
December 2011 issue of RCMW: “I’m
still hoping that the SAM organization
will come up with some type of specialty
contest using this size Old-Timer aircraft
in conjunction with electric power and
RC.”
Bob’s hope has nearly come to fruition,
except for one small detail. All the small
OT models he’s designed—except for his
micro Kerswap—are built to 200 square
inches. Their wingspans are roughly 50%
longer than the 24-inch span limit for
Small Old-Timer events.
Bob’s available plans could probably
be resized to fit the criteria and still be
usable. He supplies complete technical
data for each design, including exact
recommendations for batteries, ESCs, and
motors. Those might have to be reduced
as well, but fortunately there’s enough
lightweight electric gear available to
allow that.
I recommend Bob’s instructional CD
book, along with RCMW, if you have an
interest in these small electric models.
The plans are also available through
RCMW. If you have limited space for
building or flying, this would be a great
way to go.
If you’d like a break from buying ARFs
and want to develop some actual modelbuilding
skills, this would be an easy way
to get in the game. Check the “Sources”
listing for Bob Aberle’s book and plans.
SAM Champs 2012
SAM Champs 2012 will be held
at the AMA National Flying Site in
Muncie, Indiana, September 10-14. Jim
Coffin will be contest manager, with
separate CDs for RC and FF events.
By the time you read this, there should
be complete information and entry
forms posted on the SAM website. See
“Sources” for more information.
Crash ’n Bash
SAM Chapter 21 has been scheduling
its annual Crash ’n Bash either a week
before or after the SAM Champs. This
allows a few fliers from overseas to catch
two OT RC events while in the US.
It’s held at the Schmidt Ranch, a few
miles south of Sacramento, California.
Check the AMA contest schedule later
in the year for details of the September
21-23 event.
US FF Championships
US FF Championships will be held for
the 42nd time, September 21-23 at Lost
Hills, California. In addition to modern
AMA and FAI events, there will be 16
OT events and 10 Nostalgia/Classic
events. Besides a number of perpetual
and other trophies, there will be cash
awards totaling more than $4,500. See
“Sources” for contacts.

Bob’s available plans could probably
be resized to fit the criteria and still be
usable. He supplies complete technical
data for each design, including exact
recommendations for batteries, ESCs, and
motors. Those might have to be reduced
as well, but fortunately there’s enough
lightweight electric gear available to
allow that.
I recommend Bob’s instructional CD
book, along with RCMW, if you have an
interest in these small electric models.
The plans are also available through
RCMW. If you have limited space for
building or flying, this would be a great
way to go.
If you’d like a break from buying ARFs
and want to develop some actual modelbuilding
skills, this would be an easy way
to get in the game. Check the “Sources”
listing for Bob Aberle’s book and plans.
SAM Champs 2012
SAM Champs 2012 will be held
at the AMA National Flying Site in
Muncie, Indiana, September 10-14. Jim
Coffin will be contest manager, with
separate CDs for RC and FF events.
By the time you read this, there should
be complete information and entry
forms posted on the SAM website. See
“Sources” for more information.
Crash ’n Bash
SAM Chapter 21 has been scheduling
its annual Crash ’n Bash either a week
before or after the SAM Champs. This
allows a few fliers from overseas to catch
two OT RC events while in the US.
It’s held at the Schmidt Ranch, a few
miles south of Sacramento, California.
Check the AMA contest schedule later
in the year for details of the September
21-23 event.
US FF Championships
US FF Championships will be held for
the 42nd time, September 21-23 at Lost
Hills, California. In addition to modern
AMA and FAI events, there will be 16
OT events and 10 Nostalgia/Classic
events. Besides a number of perpetual
and other trophies, there will be cash
awards totaling more than $4,500. See
“Sources” for contacts.

Twin winter Old-Timer (OT)
contests are held each year in
mid-January. Both contests are
in warmer climates at opposite sides
of the country.
The relatively new Eastern event
was in Dade City, Florida. Barbara
Mulholland is a skilled OT RC  ier
who helps with the contest. She sent
this note about the Florida event:
“This was no doubt the best one so
far; three sunny days with reasonable
temperatures, but at times, annoying
winds. There were 25 contestants from
eight states and Canada—the most
we’ve ever had.
“We feature all the SAM [Society of
Antique Modelers] RC ignition, glow,
and electric events. Tom Boice helped
provide Winter-Fly coffee cups in
memory of his father. These cups were
given to each of the contestants and
were a big hit.”
In the West, I attended the 2012
Southwest Regionals (SWR), held in
Eloy, Arizona. The SWR was in its 67th
year. Great weather was enjoyed at this
end as well. It’s a much bigger contest
because it includes OT RC, but adds
OT FF, plus modern AMA FF, FAI, and
Nostalgia events. If you live in snow
country, why not plan to attend one of
these events next January?
Model Visibility
Model visibility at altitude during the
SWR was the best I’ve seen anywhere.
There was a thin, high overcast that
backlit any color scheme and made it
stand out as a silhouette.
Usually, no single color scheme works
best for all lighting conditions. Black,
or other dark colors work well against
white clouds, but fade out against a clear
blue sky. Lighter colors, such as white,
yellow, or orange seem to work well
against a clear sky, particularly if they’re
translucent.
It would be nice if contest managers
would arrange for a mix of blue sky and
white cumulus clouds so we could  y
under the area best suited for our color
scheme.
Obsolete Fuels Recalled
It was probably in the 1950s that
modelers began buying premixed fuels
instead of mixing their own. Answering
a question in the February 2012 column,
I mentioned that glow engines could be
run on gas and oil mix (no methanol)
if run fairly fast
and warm.
I received
this note from
George Lieb,
from Omaha,
Nebraska:
“Slow engines
also run  ne on
gas and oil—if
you add nitro
propane. I used
it in my K & B
.29 in my AMA
Team Racer in the 1950s. I don’t know if
or where it’s available anymore.
“We used 25% 70-weight motor oil,
Amoco high-test white gas, and about
20% nitro propane. It ran slower than
glow fuel, but way longer. We got about
half again as many laps as on glow fuel.”
Thanks, George. The idea was to run
more laps using the speci ed small tank
size, so you made fewer fuel stops. I
recall using nitro propane to give some
extra punch to gasoline, much the way
nitro methane does in glow fuel. But
that still didn’t allow gas to match the
power of glow fuel.
SAM competition rules today prohibit
using nitro in spark ignition engines, so
that rules out nitro propane and nitro
methane.
Another obsolete fuel ingredient
is nitro benzene. Even used in small
quantities, you could instantly recognize
it in a fuel mix because of its shoe
polish-like odor. I disposed of my
remaining supply many years ago after
learning of its highly carcinogenic
qualities.
Scale Documentation
Bob Banka sent a note regarding his
scale documentation service. He’s been
in business for 30 years and says he has
the world’s largest collection of photos
and three-views at 50,000-plus pages.
After looking at his website I certainly
believe it.
Bob covers more than I can begin to
address in any detail here.
Besides conventional models,
he includes Sailplanes, helicopters,
gyrocopters, engines, and some
weaponry. Most of the aircraft are old
designs. He has sales agents in half a
dozen countries outside the USA.
Prices for three-views start at $3 and
up. Bob’s Foto-Paks range from $6 to
more than $50 for some subjects. Spend
some time browsing his website. See
“Sources” for more information.
Walter Craig’s Engine Services
Engine services provided by Walter
Craig were announced in my February
2012 column. I mentioned that I had no
direct experience with his work, but had
heard no complaints.
Harvey Hartman of Waller, Texas,
used Walter’s services and sent a note
expressing his satisfaction. Here are
Harvey’s comments:
“I sent Mr. Walter Craig three vintage
ignition engines that I purchased on
eBay last year. Old ignition engines are
new territory for me and even though
I suspected they were in good shape, I
wanted an experienced eye to look them
over before I tried them.
“They were disassembled, cleaned, test
ran, and returned within two weeks. His
price was very affordable and he even
included a letter with recommendations
for prop sizes and fuel blend.
“Throughout the process, he kept
me informed via emails. I like that! I
now have three good-as-new vintage
sparkers ready to fly. I can thoroughly
recommend Mr. Craig’s services!”
Small Old-Timers
Small Old-Timer describes a model
category and a loosely organized group
of fun fliers spearheaded by SAM
secretary, Tommy Gray. This year they’ll
be flying once more as an added event at
the SAM Champs.
If outdoor winds are too high, the
group is looking at the possibilities of an
indoor venue. The models are scaleddown
versions of full-size SAM-eligible
designs. Wingspan is limited to no more
than 24 inches.
When I first heard of this movement
a few years ago, I envisioned a mix
of electrics and maybe .010- or
.020-powered FF and RC aircraft.
Practical matters seem to have narrowed
it down to electric-powered RC only,
but I doubt that you’d be thrown out of
an outdoor fun-fly event if you showed
up with a .010 “nitro”-powered aircraft.
Further information and the few
rules are posted on the SmallOldTimers
website, listed in “Sources.”
I had mentioned these small models
in the February 2012 issue of the SAM
26 newsletter, which I edit. Bob Aberle,
MA’s Technical Editor, saw a copy and
sent me a CD with data about the 10
small, electric Old-Timers he’d designed
and built for RC Micro World (RCMW)
magazine. John Worth started RCMW
several years ago, and after he passed
away, Roland Friestad revived it into an
electronic-only publication.

Bob Aberle is a prolific builder and
he didn’t stop after designing those 10
small OT models. He produces nearly
one a month, although most are not OT
designs. He’s made a comprehensive, 120-
page CD book filled with good technical
details about small, electric models. It’s
$10 postpaid for US delivery.
Here’s a quote from Bob in the
December 2011 issue of RCMW: “I’m
still hoping that the SAM organization
will come up with some type of specialty
contest using this size Old-Timer aircraft
in conjunction with electric power and
RC.”
Bob’s hope has nearly come to fruition,
except for one small detail. All the small
OT models he’s designed—except for his
micro Kerswap—are built to 200 square
inches. Their wingspans are roughly 50%
longer than the 24-inch span limit for
Small Old-Timer events.
Bob’s available plans could probably
be resized to fit the criteria and still be
usable. He supplies complete technical
data for each design, including exact
recommendations for batteries, ESCs, and
motors. Those might have to be reduced
as well, but fortunately there’s enough
lightweight electric gear available to
allow that.
I recommend Bob’s instructional CD
book, along with RCMW, if you have an
interest in these small electric models.
The plans are also available through
RCMW. If you have limited space for
building or flying, this would be a great
way to go.

and want to develop some actual modelbuilding
skills, this would be an easy way
to get in the game. Check the “Sources”
