hey guys so i was running my twister, and i came to make a turn, but then it stopped. i hit the throttle, and the motor spun, and so did the dogbone on the left, but it doesn't seem to move. its hard to explain my problem, so here is a video of the problem.

Check the pins in the wheel stubs.

thanks! that fixed it. one of the pins had fallen out so i just put in another one i had laying around. i never knew that they could cause a problem.

No pin makes it like an open diff, will spin but wont go anywhere.

oh okay i see. thanks.
