Hello everyone, I recently dug an old car out of storage and cleaned it up for my young son. This car was mine about 20 years ago. After all was said and done, I plugged in the battery and the motor just runs without the remote. I can engage the remote to turn but the motor never stops or slows down, any ideas what I should do?
I believe this is a grasshopper circa 1987.

Thanks, sonny

if the radio is on have you checked the thortle thrim if not the esc might be bad

Thanks for your reply. Even with the radio off, as soon as I plug the battery into the car, the wheels just start spinng. What is the esc?

I would guess that you have a MSC or mechanical speed control. They normally sit on top of the chassis and have a wiper arm that attaches to a servo. With no radio on the wiper arm may be in a position to run the motor. You should be able to turn the wiper arm by hand to turn off the motor.

Thanks for your advice, I will check this when I get home.

Thanks again for all of your help and advice. I took this thing apart and found that channel 2 on the receiver was not working. I reversed inputs for steering and engine control, the engine worked fine when I changed them and then the steering did not work. I ordered a new 2 channel receiver last nigh.
