your radio pcm or ppm?> if so try each. also when you plug it in try it with throttle pulled. If it arms, THEN go a switch direction on that channel. just a coule ideas. Im having trouble with mine too!

also, adjust your trims around in the negative areas too.

They seem to be quite dependable and user friendly but right now they are the hottest thing since sliced bread. UH had 11 for like 5 minutes
