XB, throttle glitching


I have a Spectrum DX2E RX/TX and a Super bee kill switch. The steering servo is stock and I replaced the throttle servo with a HS645MG. Everything is fine until I start it up. The throttle wants to slowly go to full throttle. It doesn't stay there but will slowly move a few degrees back and forth. It doesn't seem like the normal glitch a servo would have where it jumps around quickly. I can move the wires around and keep it in neutral position, but as soon as i let go of them it moves again.


Any thoughts?
 
Could be getting interference. Try a new plug. That would be my first suggestion, since it only does it when it's running. Interesting though, how the SuperBee doesn't kill the engine when it glitches.

That's a good point. It does not recognize it as a glitch. It also doesn't act like a glitch either. It seems to move too slow.
 
I agree with the new plug suggestion, a resistor plug is supposed to all but eliminate radio interference.

Battery topped off, it's not low is it?
 
Fully charged battery and old servo fried the solder like all of them do. Trying the new plug this weekend. Thanks for all the suggestions.

If I have to I will pull a servo out of another car and try it out.

Let us know how it goes, dude.
 
I shortened the wires on the servo, put an NGK plug in and some insulating foam between the wires and the receiver in the battery box and all is fine so far.
 
Good to hear!

Bad connections, low voltage and plug interference are the most common causes.
