I have the Edge 540 and the Citabria... I found the Citabria something I'd use as a trainer. The Edge I've been using to perform stupid foamy tricks. I haven't REALLY been doing 3D hovering. Just mostly flying map of the earth and between trees in the wooded area behind our house. The Edge has REALLY taken a beating. I have hit or put it up in several trees. The foam has cracked, but after a quick zap of CA it's back up in the air.

I setup all hinges with the CA hinges. I didn't put the center plywood piece in for the elevator. I used 4 CA hinges instead. Just simply cut a full sized hinge in half, and mulah!

I'm looking forward to mounting a Black Widow Cam in one of these planes. I'm even thinking about ordering the F-18 so I can get more of a Jet feel to things!
