suggest you keep it under 7.4, because 1)the steering motor will be too fast for the board to respond, making it jumpy, 2)the motor will be way too hot even if the supension can take it. if you really have confedence in your motor and throttle, use external FETs like the v2.2. By the way, while having that many FET may increase your torque, i don't think it is that significant over 4x2, and the throttle becomes unstable by then. motors you can fit in a Mini-Z rarely even need 3x2 |
