the more I used it the weaker the motor became. It was gutless on anything but flat surface. I do tend to be a little harsh on my Trucks and push them to the limit.

For example the stock Tamiya motor in my 6 wheel dump could pull my fairly steep driveway. loaded with dirt, in 3rd gear. yes it would slow a little but it could maintain the gear.

The RC4WD 65T had to pull the same hill in 1st gear maybe 2nd. Any other gear it would over load the Speed controller and time out.

With these style of motors the brushes are a very hard compound for what they hope is long life. If they aren't broken in they tend to glaze the brushes as well as the commutator which then causes excessive arching and heat which can shorten the life and efficiency of the motor. And depending on the heat and quality of the magnets it can demagnetize them as well.
