Hi, I have had the

"M1A2 Abrams USA Battle Tank RC 16" Airsoft Military Vehicle " for about four months now. great little tank and loads of fun (especially when you fpv it) but have recently had some trouble with it.

The right track started moving slowly compared to the left, causing tank to spin in circles. I remedied this by turning tank upside down and hitting full throttle and issue seemed to work itself out and both tracks went back to moving at same speed. Today, the right track complexly stopped moving forward, but will move in reverse .
This being my 1st rc tank, I am unsure what troubleshooting steps to take to fix. Any advice is greatly appreciated.
