as the title says i have a servo problem in my firestorm i took it out 2 days ago for a bit of bashing did a few jumps and the place was really dusty so as you can imagine my car was covered with dust so after a days bashing i thought it could do with a good clean so i sprayed some muck-off on the chassis to give it a good clean and after i cleaned the car my servo was acting rather odd the thorottle servo was stuttering when put some throttle on i checked the batterys and they were fine i've opened up the servo and to me there wasn't a clear indication that it was f****d if you could please help me will put some pics of servo if needed.

Next time, just use compressed air and blow it off. If you use liquid/spray clearner and got your radio/servos wet, youll be looking to buy new ones. Stock servos are not that well protected from mostiure.
If you took the servos off before you cleaned the truck up and its actong funny, check the connections and the batteries again.
Without seeing hands on whats going on, Thats what I would check again.

ya...definatly use compressed air cleaners like computer keyboard cleaners...definatly dont use liquid cleaners unless ur servo was waterproofed along with your receiver.
