I also have a Superstar 40, its been an awesome trainer. I have somewhere around a couple hundred flights on it and 2 crashes.

I have repaired the wing a couple of times and also noticed that they did not use much glue. I have put this plane through some heavy stuff and its still going strong.

I have heard great things about hobbico and that they will look at your plane and make a decision based on what they see.

Let us know what happens
