I've actually had to epoxy the two wing halve back together twice already. I guess the stress has been breaking that bond. However, I love screaming down the runway shooting the plane straight vertical, then a quarter turn and watching it rocket into the sky. This particular trainer has a thick metal rod in the wing, so perhaps that is holding everything together. I'm building a Venture 60 kit currently, and there is no way I'll be attempted some of the same things I do with the trainer. The trainer is built like a tank compared to the Venture. There is probably twice has much wood in the trainer. The wing ribs are over double the thickness of the Venture.

Thanks Ronnie. Those cheeks do flap quite a lot. Even while on the ground, I'll throttle up on the test stand and the cheeks violently clap. I'm worried that one of these days, the fuel line from the high-speed needle valve to the carb is going to come off while in the air. I can see the left cheek actually hit it the fuel line.

I've also had some problems with screws coming loose on the engine mount and the engine back plate. There must be a lot of vibrating going on up in the air.
