Rich Weber did an excellent job on this one-of-a-kind Cessna GC- 1 Miss Blackwell Oklahoma racer.
First, he puts on rubber gloves then
razor-saws the aluminum tube near the
base of the marker, being careful not to
go through to the wick inside. He pulls
the color wick and applicator tip out and
puts them in a four-ounce jar of nitrate
Bill puts the lid on and shakes it
briskly to leach the color out of the
wick and applicator. He opens the jar
and squeezes, dunks, and again squeezes
the wick and applicator until all of the
dye has been transferred to the thinner.
He pours the thinner/dye mix into
clear dope to get the depth of color he
wants—usually about a 1: 1 mix. Red
and orange are fade resistant—blue and
green are not.
Bill noted that the Supreme Model
Company’s designs are all clumsy in
nature, with heavy wood construction
of 3/32-inch square sticks, when 1/16-inch
square sticks would have been better
suited for their small size. The plans
should be touched up to get symmetry
in the wing and stabilizer plan views.
One wing is longer than the other and
the wingtips don’t match!
The Thermal Bagger has a constant
fuselage section for its full length to
slightly past the rubber peg. It’s ugly,
but effective, for a big blast-tube
So why build it if the fuselage is ugly,
the plans have to be adjusted, and it
is engineered on the heavy side? Bill
reported that the Thermal Bagger flies
well because most of its design features
are on track. His model climbs steeply
and turns to the right in both power and
glide. Be sure to put on a dethermalizer.
The Thermal Bagger is eligible for
Flying Aces Club (FAC) Old-Time
Rubber Stick; however, as Bill put it,
“It would be like taking a knife to a
gunfight!” Thermal Bagger plans are
available from the AMA Plans Service.
Cessna GC- 1
Rich Weber loves finding obscure
airplanes to build. His Cessna GC- 1
racer, Miss Blackwell Oklahoma, spans
20 inches. It weighs 30 grams empty and
uses a 7-inch Sig Manufacturing plastic
propeller. He used three loops of 3/32
x 26-inch rubber for flight trimming,
but plans to make up a larger motor for
George Voss’ New Service
Most kits now come with laser-cut
parts, but many of us still have kits with
printed balsa sheets in our stash. Perhaps
the thought of cutting out those parts
has been keeping that kit on the shelf.
George Voss has a new service that
might be just what you need. If you send
him the printed sheet balsa, he will scan
it, create CAD files, create cut sheets,
and cut the printed parts out for you.
George will not generate parts from
plans. Sending the printed sheets lets
George know that you have purchased
the kit, not simply downloaded plans
from the internet. Email George for
details and prices.
