25 Years Ago in MA:
June 1984
The cover features author/designer Dick
Sarpolus with this month's RC construction
project: the Firebolt canard (plans set 444)
for a .40 engine. Its flight characteristics
are similar to those of any good
sport/aerobatics model, and it has an
up-to-the-minute appearance. The Firebolt
earned a second-place finish in the 1984
WRAM Show.
The other RC project this month is the
Willit by Dave Pastor. With a Cox Black
Widow engine, Ace Pacer foam wing, two
sheets of 1/8 balsa, and a few hours, you
can make this excellent flying wing. The
full-size plans are in the magazine.
Full-size plans for this month's FF
construction design—Jim Kostecky's FF
Tutor—are also in the magazine. The little
17-inch-span, rubber-powered model is easy
to build and would make a good project for
use in school instruction programs.
Julie Abel provides us with this month's
CL building project, which is the Nesmith
Cougar (plans 445). With design help from
her father, David, Julie created the
41-inch-span Scale airplane. Its straight
lines make it an excellent endeavor for the
Junior, Senior, or beginning Scale modeler.
George M. Myers brings us a report of the
1984 WRAM Show. His photos and commentary
make you feel as if you had been there.
Dick Sarpolus and Bernie Raad present a
complete computer program, in BASIC
language, to use for RC canard design. Their
article also includes Ron Van Putte's
formulas, which are useful in designing
canards as well as conventional aircraft.
Carving model propellers is almost a lost
art, with all the varieties that the
aeromodeling industry offers. However, you
still might not be able to buy exactly what
you want. Wendell Hostetler's "How to Carve
Giant Scale Props" will instruct you on how
to make your own.
Larry Kruse shows readers how to make a
few handy but inexpensive tools with the aid
of full-size patterns that he presents in
his article, "Improving by Degrees."
This issue contains the last installment
of Bob Kopski's 10-part series, titled "All
About Electrics."
You can build the Ni-Cd Battery Evaluator
by following along with an article by Frank
Kelly. His device makes it simple to check
your transmitter, receiver, or other Ni-Cd
batteries. The circuit diagram and parts
