Radio Problem

I am having serious "glitching" problems with my Airtronics radio setup. The setup is as follows;

Car: 1/10 Scale Nitro Touring
Tx: MX-3
Rx: 92837Z
ST Servo: 94757Z
T Servo: 94102Z

Problem: When the Tx and Rx are turned on the servos twitch, the twitch gets worse the further apart the receiver and transmitter get from each other. When I unplug the 94757 servo all is fine. When the transmitter is turned off all is fine. I installed the 94757 servo to another vehicle and had the same twitching problem.

So my guess is the servo is malfunctioning is some way. Does any one have any experience with something like this happening? Any and all input will be appreciated. I am thinking of sending the servo in to Airtronics to get it fixed but dont want to waste on shipping if its not the servo

Yes, I've had the same problem happen to me. My throttle servo was going bad and it made both servos glitch bad. I replaced it with another one and everything was fine. It's your servo going bad. You already did the trouble shooting by trying it with out the servo. Good job. These electrical issues are hard to diagnose.

Default servo...vr series

hi.... while we r t this topic might as well share my problem too..
my servo seems to make a lot of noise ....it does not glitch or anything...mostly after it return to neutral position there will be noise for 4-5 sec...(of course can only hear without the engine running )

maybe it should be grease or lube or something
btw the servos around 50hours of runtime... thanks

Well I am sending the radio equipment in to Airtronics to have them look at it. I will post on here when I hear back from them and maybe the information will be helpful for others in the future
