We had a speed controller blow like that last fall. We ran a demo over the summer at a local fairgrounds where we ran on the grass. After a full weekend of driving the grass had worn away & we were running on dirt. Needless to say everything on the robot was covered in dirt. We tried to blow everything out with some compressed air. I guess we didn't clean out the speed controllers well enough. We then were showing the robot at our school open house in the fall & POP & spin happened. We hit the disable switch but the same thing happened, it just kept going. After we took the speed controller apart we discovered that it was still filled with dirt & had over heated.
