Hi. What bro RTECH is trying to say is Wraith do not use worm gear. Climbing hill all the time will make the motor hot. If you do have a Worm Gear... pls post a pic of the Wraith.

If you bought a second hand Wraith you need to check that the grease in the gear are still... greasy, else you need to re-grease it. I don't know if 11T or lower is recomended. If you are not going for crazy high speed a decent 27T or 35T motor is good enough for the Wraith.

Bring your crawler down during the SGcrawlers meet. It will make it a lot easier to advise you on your requirement and problem.

A lot of factors can lead to motor overload. You got to bring down your crawler and let the SGcrawlers team analyse the problem.
Dun worry, its Free of charge.  Very Happy
