help with ca v3

Hi all please help. My cav3 was running fine. Now started saying connect to pc. Intermittently. Seams to be under harder acceleration. I've stripped everything to make sure there's no water ingress and was working fine before. Nothing happened either. Seams to happen under load too. Any suggestions?...

Good 12ga spokes generally don't break in bicycle use. They loosen up chronically, they make noise, they crack your ...

Re: Replacement motor axles

Tench is a busy guy but true to his word. Never let me down. If anyone's having problems pm me and I'll call him. I got the first axle and still perfect with loads of abuse. I highly recommend docs torque arms with them to.

Re: Qulbix raptor efficiency?

I also changed battery configuration. 48v is much closer to your speed so not loosing as much heat in your controller. Or change to a 24" wheel. Basically if you were at full throttle at full spped. Ie 20mph. You would be more efficient
