Mamba Max/Crawlmaster Sport issue

[grommit327]

I was running my rig the other day for about 10 min. Started running a course and the Crawlmaster stopped working. I've tried resetting the mamba max and it initiates ok but when I pull the trigger the ok light goes off and the motor won't turn. I did get the motor to work a bit but it wouldn't turn with load on the tires and only makes about 1 revolution before it stops working if I hold the truck in the air. Did I manage to kill the motor?
