The break was out PAST the wingtube by about 2", right where the spar changes from having a ply doubler to nothing but stiff foam outside of which is the aileron servo which does not distribute load to both wing skins. It has nothing to do with the wing tube being a cutting edge and I'm not sure there would have been any way to identify the problem prior to the crash after which we split the intact wing open to take a look at the construction.
Kudos to F3AUnlimited for providing outstanding support in the wake of this minor personal tragedy.

Sorry for your loss Pete (and Matt). In your post mortem would you say something simply wasn't laminated properly to begin with or was it more of mechanical design or insufficientreinforcing materialproblem?
Nevertheless, I have a plane coming from Xtreme (Bryan's Shinden) and am very interested bystander. I will go over the model with great care.
