Ooh yeah, reminds me that I need to contact them to see what they think. A job for this weekend.

For those that are interested, the problem is that the controller (25A one) randomly stops performing the way it should. Instead of full proportional control, it only spins the wheel in one direction with no proportionality, it's either on or off. And when joystick is released, the motor coasts to a stop rather than brakes. No reverse control whatsoever.

I've had one out of four do it, and Tony had one out of two. I'll ask Steve/Aaron about it and post the findings. Hopefully just a bug/batch issue. I'd still recommend the Botbitz controllers as the best low-cost option.
