Hi guys i need to reverse a brushless sensored motor.
The esc not have a reverse. How i can to do?

You have to swap two sensor wires and two power wires. You have 36 possible permutations of wiring. Only 8 work properly- four for each direction. You will need an amp meter to watch your no load current, as there are also 8 combinations that appear to work but have a very high amp draw that will kill the ESC or motor. The other 20 combinations don't work at all.

Good luck, it is time consuming.

In my sensor cable, there are 6 wires in the plug. Are these wires a paired item? ie A +'ve and -'ve, B +'ve and -'ve, C +'ve and -'ve

The sensor wire has a positive and negative pin, with an extra wire for a motor heat sensor. The other three are the sensor signal.

The roar handbook has the pinout. I can't find the pic I have of the spec.

Thanks for that. If you find that picture, or even a link to a thread it would be really handy at the moment.
