Stock Radio bad?

[mackanon]

I have the Savage .25 RTR. Have had it for 3 or 4 years now. Just getting close to the end of break-in with new engine. After the engine gets to operating temp the idle is really jumpy. I noticed that the servo is moving without applying any throttle or braking. There are fresh batteries in there. Any ideas?:jamout:

Honestly, your lucky it all has lasted that long. Try hooking up another servo to the channel and see if it twitches too. If it does than your receiver or radio is bad.

Fresh batteries in the transmitter and receiver or just the receiver?

It's the same with alot of AM radios. Alot of things can interfere with them because many thing create a frequency similar to AM radios. The servo moving around can be caused by even a loose screw some where wiggling around. Using FM radios is better but going to a 2.4GHz radio is the best option. As for it only doing this at an operating temperature has me a little confused though.

Check your crystal too. Sometimes bashing vibrates them loose. I used to put a ziptie around mine.

I agree with grumpy- All the issues I have had with stock radio was always crystal related.
