Airplane Association’s invitational fly-in is held annually in late August in
Blakesburg, Iowa. The fly-in features
everything from antiques to modern
Scale at the Nats
You may have seen some models
several times, which could be because
of the growing number of ARFs. The
popularity of models such as P-51s and
Thunderbolts has fluctuated.
We have seen fewer scratch-built
models during the past few years, so
when a competitor appears with a new
scratch-built model of a 1930s biplane,
other pilots are excited!
Larry Botsford brought a Fiat C.R. 32
to last year’s Nats. The full-scale Fiat
was designed and built in Italy in the
1930s. The compact fighter had a 600
hp Fiat A. 30 engine and was fast, agile,
and aerobatic for a 1930s-era fighter.
It was used by several countries during
its service life, but later was outclassed
by several monoplane fighters.
The full-scale Fiat C.R. 32 was
flown by Gruppo Commander Andrea
Zotti during the Spanish Civil War.
The group commander’s pennant was
painted over the all-black roundel on
the fuselage sides and on the top of the
Spanish Nationalists during the latter
part of the war.
Larry’s 93-inch wingspan Fiat
C.R. 32, powered by an O.S. BGX two-stroke engine, performed flawlessly.
He used a Spektrum radio system with
six servos. He covered the model with
fabric and fiberglass, then painted it
Models. Larry used balsa, spruce,
and plywood to build the model and
designed his own fiberglass parts.
Larry also designed the plans, cut
out all of the parts, and made the
molds for the glass wheel pants and
cowl. This is scratch-building. The
three-views or scale drawings were
from Peter Westburg.
AMA has a class for scratch builders:
RC Designer Scale (also known as
Museum Scale). The most unique and
best-built models are in this class.
