Its the rtr brushless version, and the motor/esc are band new as well as the truck. Also it is using brand new Reedy 2s 5000mah battery. I forgot to mention, this is not when the motor/esc is on. It is when it is just off and I roll it slowly across my desk it will click click click to turn the rear whels, but if I push a little harder everything is fine and smooth. I guess I will look into the diff's and see if there is anything wrong there.
Is there anyone else out there that this motor esc combo in their sc10 and have this weird resistance when pushing the truck at slow speeds!?!?
Thanks again!
