Carl Sikora’s (Morristown, New Jersey; email: csikora319@
optonline.net) Hurry-Up 150 rubber-powered flier was built from full-size plans designed by Frank Zaic and featured in the August 1950
Flying Models magazine.
The Hurry-Up’s wingspan is 36. 5 inches. The fuselage is covered
with silkspan, and everything else is tissue. Carl noted that the
airplane is an excellent flier. “I have been in the hobby since I was
12 years old. I am now 80!”
Gary Smith (email: firstname.lastname@example.org) scratch-built this
1/4-scale Wittman Tailwind from three-views. The Tailwind is a
civilian homebuilt designed by Steve Wittman in the 1950s.
“The first time I saw a Tailwind, I knew it would make a great
model,” he wrote. “I couldn’t find the right size plans, so with help
from my friend, Orin Brenning, we drew our own. I even used the
scale airfoil. It flies very realistically.”
The model weighs approximately 8. 5 pounds without LiPo
batteries, uses six servos, and is covered with UltraCote. Control is
by a Spektrum DX6i operating four channels, plus flaps.
Gary hopes to enter a few Scale contests with the Tailwind. “I
chose electric power for dependability and minimal vibration,” he

Jimmy Franklin’s Biplane
Glen Herring’s (Friona, Texas) aircraft is a replica of the late
air show performer Jimmy Franklin’s Waco UPF- 7. The 88-inch
wingspan airplane is from a modified Barth kit, and powered by
a Moki 150. AMA Youth Ambassador Andrew Jesky flew it for its
Glen bought the kit in 2014. Rick Clarke, a retired surgeon, did the
building. “I am so proud of the finished product that I just wanted
others to see how it turned out,” he wrote.
“Jimmy Franklin was a very close friend and upon his tragic
death in 2006, I believe, I started to think about getting such an
airplane built. I don’t plan to fly it often because it cannot be
replaced. It is one of a kind, in my opinion.”
