|  tire speeds front-to-back with dual esc
I am running dual XFRs on a stock Bully, controlling with a 4pls. I seem to have trouble with getting the front tire speed to match the back. I hotwire the ESCs to the same settings, and can get the tire speeds equal in a forward direction using the throttle mix trim, but in reverse the tires are once again at different speeds? It takes about a 30% bias to get them equal. I have gone thru the Tx menus but cant see anything that might cause this. What am I doing wrong? Or is this normal? |

Did you calibrate each esc seperatly ? Cause ya gotta do that before messing with settings

Yup calibrate them separately then do settings in each one. Probably something I'm doing just threw it out in case anyone has seen it with their rigs... |

All motors are not created equal, have you verified the timeing ? That could cuase the exact issue you are having....

Huh, maybe I will need to spend some $$ on a pair of good motors, these are ten buck specials, the bellcap does not appear adjustable. 30% difference forward, 40% in reverse. |
