My primary reason for starting this thread was to help me know how to
evaluate whether an FX-67 winged glider has suffered from "spar
shrinkage" and if so, how much and how badly it will impact the
performance. I've heard so much about and that it can profoundly
decrease the performance so I'm trying to figure out whether to worry
too much about it. As a relative newcomer to working with composites
I'm not sure I could actually fix it...or might make it worse.


Thoughts?

Personally I think there is a load of BS spoken about performance,
biggest improvement in performance in my humble opinion is pilot
improvement. I suspect you would spend hundreds of man hours trying
to make the wing shape perfect and it won't alter your cross country
ability one bit, spend the hours flying and / or save hard and buy the
best new glider on the market today - whatever that is!
