|  AX10 lurches under high torque?
Hi there, I have a Axial ax10 with 4WS. Front servo is a Solar D772 and rear is a Traxxas 7072. It has the Axial 55 turn motor running off a castle SV2 with a external castle BEC. I use a 3s battery. When I get in a higher torque situation it lurches back and fourth violently. I just put in a new BEC thinking that was the problem but no luck. The Bec is at stock settings. Can anyone help me with trying to figure out why it lurches under high torque situations? Thanks tons in advence!  |

I've never encountered the word "lurching" used in this context. Please describe in other words what happens. Does the wheels spin slowly back and forth? (Wouldn't be "violently"...) Not spin at all? Vibrate? Is it the body that rocks side to side? |

I *think* he is describing glitching with the motors suddenly engaging. Is it worse when your steering is under heavy load? I have had this issue on my x-crawler, usually when the truck is in a tight spot and both axles and (high torque) steering servos are working hard. At first I thought it was interference (doesn't hurt to check the wiring) but after I eliminated that as best I could I've put it down as possibly the ESC struggling with the current draw of everything in those situations. I also experienced no change running with or without a 5A BEC. |

I kinda thought that word might get some comments  But ya...glitching is a better choice of words. The truck tries to go forward, then releases power, then forward, then releases, etc. Probably at the rate of three cycles a second. So the wheels go back and fourth quickly shaking the entire rig forward to aft. Thanks! |

What size battery (C rating)? Did you try a different battery, maybe you have a bad one.
