ESC Problem, please help??


Hello, I have a Rondo 400 ESC on a 6v speed 400. I have run it before perfectly fine. I am building a pusher and realized that the prop was spinning the wrong way. So I cut the wires and soldered the + to the - and vise versa. I plugged in my battery pack and the prop started spinning at full speed, my radio had no control. I moved the motor controll all up and down and the motor kept running at full speed with the battery pack attached to it. Does anyone know what this is and how to fix it? Thank you very much for input!!

You moved the + and - going to the motor right? if you did it on the battery side of the speed control, you may have fried it.

If your Rondo is like mine and designed to be soldered on the motor itself, you cannot change the direction of the motor by reversing the polarity on the inputs. The input polarity must be correct for the ESC to operate and only works one way. You must remove the ESC from the motor, rotate 180 degrees and resolder to the motor. Or, do like I did and solder leads from the ESC where it should fit and be soldered on the motor, then run the wires to the motor terminals.
