The Hobby Shack Cirrus Sport Four, 4-Channel Radio Control System was my second
radio control system after the OS
Digitron DP-3, 3-Channel system I bought used from a man down the street from
where I lived. The Cirrus was very prone to metal-to-metal noise interference. I
had to use nylon clevises on the engine throttle control arm because with a metal
clevis the servos would chatter nervously. The situation was really severe when
I used the Cirrus radio in my DuBro Tri Star helicopter, where the metal main rotor
and meshing spur gear on the engine caused major interference problems. Wrapping
the receiver in tin foil took care of most of the problem. A metal case on the receiver
would have probably eliminated the need for further mitigation.
