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.
