hi all
my car reciver was running on low batteries just now and i just changed it...when i changed it the throttle servo was glitching just a bit and the steering servo will steer left then make cracking sounds! it's not from the servo because this is my third so far..every time i put a new one the same cracking sound comes whenever I TURN ON THE TRANSMITTER when i turn off the transmitter everything is ok?? any help? hobby store guy just keeps saying its the servo and i just got this yesterday..i only drove for a bit with no crashes.. i was just finishing the tank

when you replaced your servos did you zero them out? Plug the servo in and turn the car on, not the transmitter, this will zero the servo out and, very important. other than that sounds like it could be water damage.

i did zero them out.. i even took off the servo arm to zero it out...plus whenever i turn on the transmitter whenever i move the tires its has a lot of pressure..hard to push but when i turn off the transmitter its all ok... i think its from the transmitter...

plus my car hasn't touched water since i got it! i only clean it with air and a toothbrush
