T’rex Chassis gearbox

[ryanbuiltthat]

I recently purchased the T’Rex tank chassis and am having issues with the right gearbox. I read some of the comments on the product page that sounded similar to my issue. Basically the left runs fine, but the right track will barely move. If I apply power directly to the motor I can get the track to move but it it very loud and the current jumps way up as if it’s under load. Has anyone else encountered this and come up with a solution? It’s a fantastic platform but not much use if I can only go in circles :?
