Hank Sperzel’s P- 30
rubber hook, made
from a cotter pin, is
installed on his P- 30.
Scott’s class used kit-supplied stick-on
circles to hold a joint in place, flipped
the model over, and applied and rubbed
in slightly water-diluted aliphatic glue to
the joint. (Diluting the glue is thought
to help it penetrate the wood.)
After the joint dried, the model was
flipped back over, the stick-on circle
removed, and the upper side of the
joint was given the same aliphatic glue
treatment. This manner of gluing the
wing joints was found to be strong.
The Mountain Lion kit is available
from Laser-Cut Planes, which is based in
Colorado Springs, Colorado. Although
the line began with
indoor model kits, a
couple of outdoor models
have been added. The
company also carries
propellers and nose
P- 30 Rubber Hook
Hank Sperzel showed
me his rubber hook
made from a cotter pin.
He claims the hook
is cheap, simple, and
effective for P-30-size
rubber motors. The
picture tells it all.
