Hi Nick. I don't mind you asking at all, I am using a 12V 300watt 13 pole motor out of a Holden Commodore air fan, For some reason the esc wouldn't handle that motor, it works fine on other motors. Dave at Action offered to supply me with another ESC, (FOC). But I declined the offer & decided to have a talk to my local electronics man to see what he could come up with. Dave at Action is excellent to deal with & I sure he would have come up a fix if I had given him the chance to do that, As he said it would be difficulty to have the right gear for every motor that modellers want use in their models. I decided to keep his Action ESC to use in a smaller model nothing wrong with the ESC they are well put together.
If you are looking for a 24 volt ESC check out the site I have listed below they sound good.
