Hi, the same happens to me with my converted Wheely King. After installing the reduction gear from the crawler upgrade, the motor, esc, and reduction gear gets too hot in my opinion. It also sounds as it is having extreme friction inside. The manual didn't specify whether or not to put grease in it, as it did specify it with other parts, so I didn't use it.

Anybody knows if this is ok?
