buggy gearing -
05.29.2013, 04:22 PM
I have a 7.5lb AE buggy fully loaded. I am running a 2650 on 5s with a 17t pinion. Motor gets hot and other stuff is cool.
Geared too short or is 5s borderline too much? |

Speed calc says you are geared for 70+mph and 50k RPM on the motor. I'd say that's overgeared and too much voltage for the motor. Even with lower gearing Castle recommends 4S max on the 2650kv. The 1800kv 1512 is much better suited for 5-6S.

5s is okay, the castle 15xx series of motors don't mind 50k rpms. Definitely get a smaller pinion, aim for a top speed of around 50mph.
It's "Dr. _paralyzed_" actually. Not like with a PhD, but Doctor like in Dr. Pepper. |

The esc and battery are cool though.
Its a RC8.2e, I think 17t is a stock pinion. What calculators are you using? |

I will try smaller. Speed calculator said 80+ on a fresh charge.... No wonder it never stopped accelerating!
The holes I cut in the body helped a lot, focused the air over the motor. |
