A friend of Kenneth Karpinski’s (email: firstname.lastname@example.org)
brought him a Sterling Ringmaster powered by a McCoy . 35 engine that
was built by the friend’s grandfather in approximately 1960. It had been
sitting in his attic for a long time and the friend wanted to give it to his
grandson as a Christmas present.
Kenneth stripped the covering from the wing and covered it with
aluminum Solartex. The remainder of the airplane was spray painted
with aluminum paint. His friend wanted it to look like a warbird, so
Kenneth turned to Callie Graphics for a D-Day P- 51 scheme. The McCoy
. 35 engine was disassembled, cleaned up, and restored to running
condition with a Master Airscrew propeller on the front.
When Kenneth returned the model, his friend didn’t think it was the
same airplane. Needless to say, the Ringmaster was the grandson’s
favorite Christmas present. The young man is now the proud owner of a
model aircraft that was built and flown by his great-great-grandfather!
Citabria Model C
Brent Winner (email: email@example.com) sent in a letter
and pictures for his friend, Jim Coveney (St. Petersburg, Florida). Jim’s
designed and scratch-built Citabria Model C features the original factory
paint scheme and is covered with Koverall and dope, Rust-Oleum, and
clear polyurethane paint.
The airplane took a year to build, spans 74 inches, is powered by a
1978 K&B . 61, and is controlled by a six-channel Futaba 2. 4 GHz radio.
Jim noted that the last time he had an airplane in the pages of Model
Aviation was August of 1996, when he had a feature article about a
“I know Jimmy is so proud of this plane,” wrote Brent. “It’s beautiful!”
Paul Lindewall (Boiling Springs, South Carolina; email: plindewall@
outlook.com) submitted his Tigercub, an electric-powered, park flyersize ( 39.5-inch wingspan) version of the classic Tiger 60 and Tiger 2
models by Carl Goldberg. His smaller version was designed in CAD and
built from a laser-cut short kit.
“I’m happy to report that it retains all [of] the excellent flight
characteristics of its larger siblings,” wrote Paul.
The custom graphics were created by Paul’s wife on her crafting
machine. Free PDF plans, CAD files, and the build log of Paul’s Tigercub

Thermal Charger Joint Build
Larry Oslund (Crossville, Tennessee; email: bwofskps@
passportamerica.com) is a member of the Cumberland County RC Club
in Crossville, Tennessee. He wrote:
“This [sailplane] was a joint venture build by (L-R) Jerry O’Keefe, Phil
Klintworth (an AMA Hall of Fame member since 1991), and myself. The
Thermal Charger was expertly framed up by Phil in 1990 and put aside
until 2014 when [it was] passed to Larry to complete with one request:
[Phil] wanted to see it fly! It was the task of Jerry to cover it in UltraCote,
which would reveal Phil’s workmanship.
“Larry completed the build via power by [an] AXI [motor] and
guidance by a Spektrum DX7s. The project made its maiden flight,
piloted by Larry at a club meeting, with Phil by his side. He reported that
it is a smooth-flying sailplane and cuts a beautiful line across the sky at
Altitude Limited Electric Soaring altitudes.”
