Icebird, glad your having good luck. I put mine through the ringer also and it was built bone stock with an OS .50 and the fuse broke in two. That's a fact and I have a couple of hundred airplanes under my belt and this one was built right. My comment was aimed toward not needing wing center section reenforcement but if you want to beef something up make it the fuse. No more than 1/2 oz of reenforcement needs to be added to the fuse to make it bullet proof by way of some 1oz. glass cloth and some CA between fuse side and doubler. Try your parachutes with a push and report back, it could be spectacular!

Happy flying,
Rob
