uuuuummmmmmm! I don't worried about what will happen to the airplanes after she crash....I did not do fiberglass and I agree with Iceberg....an airplane will gain quite a bit of weight with a little mod here and here....ect., try building any plane with a gram scale to weight everything, you will quickly see what I mean.
I try to build has per the plan...otherwise designing my own airplane would make sure they are built the way I like...
