I have seen mention of wing failure a couple of times in this forum and i have probably read about 40% of the threads.

I have also read a couple where people felt or found rib damage when they unpacked their plane. I wonder if those that had wing failure may have had some unoticed shipping\packing damage that weekend the wing.

Also i wonder if there is any correlation between wing failure and Saito 100s.

Not that I dont think this plane would fly great with one, and am considering it myself, buuuuuttt, just maybe it has something to do with it.
