This was a pullout plan from an old issue of Model Airplane News that
my buddy,
Rob Stahlman had sitting around, collecting dust. I looked it over
and figured it'd
make a great 3rd airplane for me. It looked about the size to be powered
by an .05
motor. I just happened to have an AstroFlight cobalt that was begging
for a new
airframe. I put it onto a beltdrive driven by 8-1700 SCRC's and a 10
X 10 APC
prop. The honors were given to Ray Gagne, test pilot for Diablo Valley
Radio
Controllers. He did a beautiful takeoff and flight followed by
a rolling 2 wheel
landing. The total flight time was just under 5 minutes. That's me
with the smile
holding the model after the 1st flight, Thanks Ray! Since then it has
been
repowered with the Model Electronics Turbo 10+. This swings a 12 X
10
Master Airscrew Electric prop on 10-1700 SCRC cells for a terific boost
in
power and speed. The latest specificatios are in the table below.

Looking good, needs a pilot though.
