So I bought a used MA X-Cell gasser 1005 and got around to running it for the first time about a week ago. Everything is a few years old on it since it was never updated since it was new. The servos are JR NAS 4131 all around. I initially added my JR receiver so I can fly it with my 72hz radio. I ran it but I notice the throttle and tail servos jitter running or not (every other servos is still). I swapped the receiver for a Spektrum AR7000 (and matching 2.4hz DX7 radio of course). Now the servos are still until I start the heli. Why would these same 2 servos jitter no matter the receiver? I'm under the impression that the Spektrum 2.4hz receiver would take care of any interference issues. I'm gonna swap the servos but I sure would like to know what the deal is with these two.
Any ideas?

Thanks,

KT

if the wires are running past the ignition too close, the magnetic fluctuation from that will be strong enough to send a signal down your leads. make sure the wires are run as far from the engine electronics as possible. also might try to install some Ferrite Beads on the servo leads.

Could be that the feed back pots in those servo's are on the way out. Try swaping them with others.
