"Sketchbook" (aka "Sketch Book") was a
regular feature in American Modeler magazine. It consisted of a handful of
construction, operating adjustments, and finishing tips and suggestions (aka
"kinks") for model aircraft, rockets, cars, and boats, all submitted by readers.
A staff artist put those ideas to drawings. This October 1958 issue included a
twin-engined control line model that claimed to fly well even if one engine quit
before the other (which was almost always the case on fuel-powered models) -
without an outboard thrust offset - due to both engines being located as close
as possible to the fuselage centerline. Another tip suggested a method for
marking and masking off complex, curved areas for painting. One reader showed
how to significantly strengthen the wing-to-fuselage joint by using a simple
plywood insert.
Sketchbook
 Compact U-control twin-engine "wing" handles well on either or both engines,
claims designer-builder Ralph Hart, Colebrook, Ontario, Canada. No out-thrust on
engines.
Masking tips from famous modeler Dale Kirn, Salina, Kansas. Methods recommended
help produce prize-winning decorating, finishing.
Extremely rigid wing-fuselage assembly for profile control models comes from
A. E. Brown, La Grange, Ill. Plywood members fit slotted fuselage and leading edges,
assuring alignment and strength.
Got a new idea for construction, adjustment or operation of model planes, boats
or R/C? "AM" pays $10 for each "hint & kink" used.
