Robotech,
Please don't be offended. This is precisely why we are discussing this. I could just ignore it, and say that I didn't see it (you would be surprised at how many pilots I know take that approach). Better to talk about it and understand the problem - so if you are flying with cracked wings please let me know LOL.
The cracks appear to be surface cracks and while alarming, from the outside it appears to be just superficial. The only way to test is to destructively test it, or open the wing. I'm sure someone has the answer on this board.
Also - Dave,
While I agree with you, for 199 bucks I'll take the plane and avoid doing blenders and snap rolls. Next closest aerobatic plane is more like 330 bucks. And after all there is little stress practicing 3D on the wing, so it is GREAT for that.
