I've been trying to get these to work for the Edinburgh event to put them in a middleweight but as I believe they were commonly used in heavies I posted in here.

I have got them to the point that the interface is powering the receiver and is lighting up but cannot make the controller itself control a motor. I always expected it to be a fairly simple plug-and-play arrangement but that isn't working. Anyone any experience of these controllers?

Cheers
