Basic throttle response with brushless system

[RC-Monster Mike]

Welcome to the forums, Tom. I am guessing that you are only using 6 cells, which is a known flaw with the warrior controllers. The BEC cutoff is set at 5.5 volts, which causes the controller to cut power to the motor. A 6 or 7 cell battery pack will drop voltage below this threshold on hard acceleration/takeoff, which causes the vehicle to not move. The fix is to install a receiver pack to bypass the BEC voltage cutoff of the controller.
