Motor smoked
Just got exceed infinity ep brushless electric truck. The third time I took it out didn't get the battery run down before the shaft going on rf wheel messed up and I didn't have the tools to fix. I had only been playing with it about 10 minutes. I turned everything off but left the battery plugged in when I put it back in the box. I got it fixed last night and took it out again this morning to run it till batteries went dead. I was running it on a gravel lot today. After a few minutes it stopped and I walked over and saw a little bit of smoke and the motor smelled burnt. It is stock out of the box with the leopard hobbies motor. What could have caused the motor to smoke? It came with 8.4v 3000 mah ni-mh battery. Any idea what went wrong is it ok to run on gravel? Thanks for the help.
