You shouldn't need to do any mods. The landing gear blocks that Barry spoke of are a weak point but will last for quite a while if you take it easy on landings. I usually wait until it gets loose before I mess with them. It's not a bad ideal to reinforce them if you don't mind a small patch on the top of the wing.

I hope you make it to our race in Hesperia. Looking forward to meeting you.

Blessings, Terry
