Default exo terra getting hot

Hi, I haven't done a lot with cars. I got an exo terra last time I had surgery for something to build while I was down. It has been run a few times now and has the castle motor and speed control. I noticed yesterday that when I plugged the battery in for just a few minutes to check something, the motor got really hot. Any idea why? It seems like when I run it with a friend with the same setup, mine gets hot and his doesn't. We are both running 3 cell 65C batteries. Setups are almost identical.

Thanks for any ideas.

Check for binding in the drivetrain, clean the motor, re-do the gear mesh, and gearing. Also check for shorts. If all else fails, see if you can get a motor cooler.

I agree, a good place to start is with rolling resistance.

Its the first thing to check.

Since ur mate has one can u compare them to each other?
place them on a nice level hard surface, then push them by hand. Does ur car feel harder to push?

One good idea to that's a easy one, Double check the wheel nuts.... back the wheel nuts off a turn so the wheel just wobbles.... spin the wheel by hand and get a feel for how much force u need to turn it. now tighten up the nut..... check to see if it feels the same as it did before when u spun the wheel. do this for each wheel.... while u are doing that, it might be a good idea check for hair wrapped around the axles and shafts by taking the wheels all the way off

thanks. I will look at it. My gear mesh is probably a little harsh. I will start there.
