Throttle survo problems....

[92notcher]

The throttle survo seems to struggled with moving while the car is running but as soon as i shut it down the throttle moves perfectly. Im baffled. It only has problems while the car is running..hmmmmmm

Battery fully charged? Does servo or any wiring have any nicks in insulation?

[92notcher]

batteries are brand new, and no wiring cuts that i can visually see. The survo operates normally when the car is not running, its very frustrating.

check your slide carb on your engine.. sometimes the idle screw will scar the slide part and when there is vibration it might be causing it to turn downwards a little and could be getting hung up..

does it happen when you are pulling throttle or brake or both?

if its just when you are pulling throttle then its your slide on the carb..

hope this helps..

thats some good information ill remember for my firestorm, this car has a rotary carb on it. The problem happens on both throttle and breaking. Sometimes now it moves very slow in jumpy movements, kinda like feather on the throttle pulling the trigger in quick jults more and more.

sounds to me like ur servo is going bad, an underpowered servo, or ones that come with an rtr vehicle often go bad sooner then better servos. I used to have similar problems when I ran a hitec 625 servo or a stock servo on my throttle in monster truck, or steering in a 1/10 truck.
