The motor shaft sheered off at the face of the motor, thowing the shaft piece still attached to the motor gear. No I couldn't find it.

should I go with the same motor, or upgrade?

If upgrade, any recommendations? It came with the 3300KV 540 Novatech motor (from the website).

I am a R/C newbie, so know nothing about the motors. I have managed to upgrade the truck with all the available upgrades, minus the shock towers.

TIA,
Jason
