One other point.. I also bought the tubes from Gator R/c. I bought the 36" tubes and cut them in half.

I inserted a 2"x2" block of wood at the inside of the joining edge rib. THis was epoxied in place. I drilled/tap 1/4x20 hole and used a nylon wing hold down bolt and a 3" metal strap. If you have the wings sheeted you might have to cut into the bottom of the sheeting to insert the wood block. Not a big problem. Once you glass over the sheeting and paint it no one will ever know.

THis system is really easy to use. Bill watched me set up and it only takes minutes at the field. I put the fuse with wing center section in the pick up bed, then the wing ends in the cab. Set up is about 10 minutes total at the field.

WARNING.. I do tape the servo plugs from the wing so they won't pull apart in flight. Would not be a good thing to have no engine or aileron control..
