Frank, Thanks for that, I have just ordered my C6C (cant find my V1 in garage/mans land), and will be ordering my controllers shortly, and will let you know how it goes.

I've used similar uni-directional kits from QKits for speed control of elevate and rotate motors. The MOSFETs specified in the Oatley kit are certainly sufficient for a 250W motor and the design is simple enough that you'll be able to repair them if something fries one day. The added bonus is that they accept servo signals as input, which makes them useful in more applications. That said, you'll only be able to truly determine if it works well by purchasing one and testing it. If the circuit is designed well, the FETs will not generate too much heat even after repeated stopping and starting and the motor "whining" at low speeds will be minimal. When using two such single-motor controllers for tank-style steering, you also need to remember that the radio gear or the C6C will have to do "channel mixing". The C6C provides tank mixing of joystick channels for that very reason. Some R/C systems provide mixing, others do not. For R/C systems without mixing, you can also buy a mixing circuit to work between the R/C receiver and speed controllers. I've used a couple of Oatley products over the years and they all appear to be good deals. My only problem has been that orders take a long time to be shipped to the U.S., but maybe that has improved in the last couple years. Frank P.
