John, I have never set one up and really know nothing about them. I just flew the plane for the fellow at a big IMAA event. I have flown one of the planes at the lake bed and it fought me too. I haven't even read the instructions for the unit but I'm sure it was the set up wasn't correct as you say. Not my planes, not going to fool with them. I just happen to see a use for them. I'm not going to be flying from a boat any time soon though. Just remind me about the float fly this year so I don't forget about it again.
