25 Years Ago in MA:
September 1984
The cover features Karen Haffke with her
dad, Henry's, 1/4-scale Gee Bee Senior Super
Sportster Model Z (plans set 452), which is
this month's feature RC construction
article. The 71.5-inch-wingspan model is a
faithful replica of the racer that won the
1931 National Air Races at Cleveland, Ohio.
The author's version flies well with a
side-mounted .91 Webra engine.
Clarence Mather's Sweet P-30 (plans set
454)—the winner of the 1984 US FF
Championships—is presented this month. It is
easy to construct, and the text provides
excellent information for those who have
only modest model-building experience.
Bob Palmer designed the original Smoothie,
and this month Larry Kruse presents us with
the CL Profile Smoothie (plans set 453).
This version for a .35 engine retains the
classic lines, in an easy-to-build package
that is fun to fly.
David Haught has designed a drawing table
that can be constructed easily and
inexpensively. His article includes plans
and a materials list that is easy to follow.
Don't miss the second part of Don
Berliner's "75th Anniversary of Air Racing."
Dick Everett provides a report, with
pictures, of the U.S. Free Flight
Championships held in Taft, California. This
year, Iowan Mark Sisk took home the Grand
Champion Trophy.
Richard L. Perry's article tells you how
to modify your Ace R/C TachMaster tachometer
to accurately read slower-running geared
engines' low rpm without affecting high
scale operation for faster-revving glow
engines.
For those of you who have been struggling
with switchable radio frequency (SRF) RC
systems, George M. Myers' article provides
the direction for making SRF antenna flags
with the capability of easily changing the
channel numbers.
New products for this month include a
flexible exhaust system for $19.95 from
Condor Hobbies, SuperTigre's "Bull Ring" .40
engine from World Engines, Tower Hobbies' HP
.49 four-stroke engine, and Ace R/C's
Chargemaster, for $46.95, that can
simultaneously service two transmitters and
four receivers overnight.
