Don't do it. I wouldn't pay more than $150 for one of these brand new in the box. There is too much reinforcement you need to do in the wings and the stabilizers. Brand new, these were $350. That's nuts for a plane that has such bad engineering and production problems. I removed all the sheeting from the main wings to reinforce the spars and the wood used for the main wings are a joke. It's an accident waiting to happen. If you're experienced with building and have a bunch of ARFs under your belt, you can give it a shot. But as I stated, I wouldn't pay more than $150 for this thing. It's way too much work.
