FMA Direct CO-PHot
by Gerry Yarrish
ne of the newest devices to aid us in flying our models is
the Co-Pilot Infrared Stabilization System from FMA
Direct. For this article, we really put the Co-Pilot through
its paces by installing it and testing it in three different types
of airplanes. We tested it in the Multiplex Brummi, a sim-
ple, 3-channel electric high-wing trainer, and also in Hangar
9's high-performance, low-wing glow-powered ARF, the
k
Advance 40. Then, to completely change things, we
installed it in the JR Ergo Sport, a
fully aerobatic .60-size heli-
k copter. The Co-Pilot handled

We're sure you'll be as

receiver system. The unit is very easy to

and helicopters. The unit comes with a
24-inch ribbon wire to connect the
sensor head to the microprocessor
controller unit.

roll independently.
