RCKen - I agree and disagree. Most trainers do not need the additional "glassing", but I have seen some students over the years that have snapped a wing. I know that my previous post was wordy, but it works and only takes about 15 minutes total to do (to a kit). But, since most trainers today are ARF, doing anything to the wing is tough (I've even put packing tape over the joint to help reenforce the wing - but only on ARFs, not kits) . Mr. Meyer, I concur with what your instructor says - don't fall in love with the plane. If you fly it, one day it meet its demise. But hopefully when that happens, you'll have a couple more to replace it.
