I have about 30 flights on it so far. No problems with the wing tube. I am flying the Intermediate schedule, which is easy on the airframe (no snaps). I have pulled thru some high G loops, inside and outside...no problems. I think after the shear webs are fixed, you will be fine. As a side note, The Hobbyking F3A motor is doing fine, and after a complete Intermediate routine I have approximately 25 to 30% left in the LiPos..(5,000 ma).
