I did a little practice run today, and the car was working great as usual.
I noticed the batteries were hot when I stopped, and looked over the car to see if anything was binding etc.
I then noticed the top cover was a bit crooked.
I disassembled the car and was surprised to see that the chassis was melted.
The motor lead screw was also loose.

After everything was apart I see that the chassis has melted just under the FET nearest to the chassis.

I think it was the loose motor screw that did all this.
After changing chassis everything worked great again.
A lession learned: I will always solder my motor leads from now on:cool:
