I started on a superstar and it is a great trainer. Mine had the glued up ply wing joiner instead of the aluminum bar.

In my opinion I think some people do not glue up the wing properly and leave a gap between the two halves. I had to sand my joiner down so the wings would fit correctly, otherwise I would have had a big gap.

With a gap I think it would be easy for the wings to seperate in a hard manuever.

I put my superstar through the test, I crashed that thing so many times I lost count. Built it back up and it was in the air again like it was new.
After many crashes I did notice a small crack one day. The crack started at the leading edge right near the join of the wings and ran parralle with the join about 4 in. This was after a crash where I went off the runway and down a hill, the plane hit first on the right wing but did not break.

I glassed it with fiberglass wing tape and epoxy and it never became an issue. I flew the plane for quite a bit longer, but hit a tree with it on it's last flight. The plane tumbled from the top of the trees all the way down to the ground. I think it hit every branch that was in that tree on it's way down...lol

I can tell you that this plane will take a beating in the air and on the ground. Just make sure the wings are joined correctly and I dont think there will be an issue.

I would certainly pick this plane if I had to do it over, and have thought about getting another one just to have.

Goodluck
