quick Neu motor question

[jnev]

Are you running metal on metal gears? My E-Revo (with metal spur and pinion) does this same thing at low speeds, but sounds normal at higher speeds.

I have the same noise happen on my Jammin' at slow speeds as well. It sounds to me like it is a long beeping noise that slowly gets fainter as the car's speed progresses. I run a hardened pinion on a steel spur as well, so I think that may be the reason behind it.
