All very interesting for sure. Probably just leave it. I have crashed three times really bad the last hit so hard the rubber bands cut all the way into the leading edge to the spar. Wing did not pop off. Needless to say the thing is now flying once more. I have soloed but still have to be thinking every moment but getting easier. Love this sport and I am a old guy. Keeping the trainer Avistar, long as I can. Can not say enough about the strength of this plane. Fellow members may know t his name I have given it, Scarface like the watch takes a licking and keeps on ticking. Thanks guys. gphil
