|  Mamba 5700 Motor issue
This is a first for me in years of RC... The motor shaft just snapped while I was getting on it from around 10mph! The shaft broke clean right where it was milled down to fit normal sized pinion! |

I had the same thing happen on a Park 400 inrunner in a Slo-V. Came in for landing with throttle off. Wheels caught a rut, plane nosed over. I figured it was no big deal. Got ready to take off again, gave the plane throttle and "whirrrrrr". Had snapped the rotor shaft right where the step is. No damage to the gearbox or the output shaft on the gearbox. When they machine the shaft with a square shoulder it creates a weak point. That's why I put a taper on the shafts for my Power 10s and always tapered the shafts on the GD600s that I used to mod. |
