dehonda,
I never had any problem with the wing on my stinger breaking. However, the leading edge sheeting is very thin, so handle it with care! You can stick your thumb right through it in a hurry. What engine are you putting on the stinger? It is a very aerobatic plane with the right engine. Also, it lands so much easier than my trainer did. As I said earlier, I crashed my stinger (disorientation), and the wing is the only thing that survived. I really like the wing, so I put it on my alpha 40 trainer by hanger 9, and still fly it on occasion. Just use 30 min epoxy to glue the wing halves together. I used the supplied hardware, and it never failed me, but I was constantly worried about it!
The stinger has a forward gear mount for mounting skis and such to. It is directly below the leading edge of the wing. I thought this would be a perfect place to put the main gear, and make it into a tail dragger. The gear kept breaking out, and I never really like it much. I converted it back to trike. Moral of the story--it doesn't make a very good tail dragger.
