went through a couple of tanks, been about a month since I have ran it and at the end of the run you push the car and you cant move it, it binds and wont move, im thinking something in the transmissions? any help from anyone thanks

Turn the transmiter off, and the receiver and open the trottle manually. Now try to roll it. If it is free, check it again with the transmiter and receiver on. If it is binding again, your brake is coming on at idle, and needs to be adjusted.

nah its not that, it binds when I move the spur gear, and its not the mesh checked it numerous times, I think in the transmission shaft the pins sheared out inside, just wondering if other people thought the same

Make sure the one way bearing is not locked on the shaft. Turn the spur gear by hand in one direction and see if the truck moves. Then spin the spur gear the other direction. One direction should make the truck move forward and the other direction will spin free and the truck tires should spin. If it does then the one way bearing is lock to the shaft. If it is then free it and replace the one way bearing. Also check that the brake is releasing the breaks. With the truck on the ground and not running use the radio and press the throttle forward and see if the truck rolls freely.

Your sure its not the brakes? I have heard of problems like yours before, and the brake was just coming on.

The top drive gear has been know to shear off the pin if the one way bearings is jamming.

I would imagine almost no resistance and no power transfer if you have a sheared pin...

Exactly, but if the brakes were on, they would release as the throttle turned up.

I have seen the cliper lock and not release the rotors.

no matter full throttle it still binds.

Is there a wobble in the spur shaft?..

Does it move at all? it cant bind and move at the same time...

You know what this means. If is surgery time. Pull the tranny out and turn it by hand. If it binds open it up and look inside.

yeah not matter if you give it full throttle, or you push the truck by hand it just binds doesnt move at all

Binding is motion with resistance..Can you post a video of your issue? So the truck wont move with out the tires slipping on the floor if you push it...and the spur gear wont move AT ALL to turn the tires?
