I had a fellow give me 1/2 a wing and a busted fuselage and I rebuilt it. First was taking of the covering that he applied with it seemed to be a thick paint of some sort and all the repairs from previous crashes. Made anew wing half fixed the fuse and installed a Super Tigre 2500 witha 7d carb. This thing recovered with monocoat is still really heavy and I really do not want to know how heavy. It flies reallygreat. t slow lands at a crawl and is a very responsive ship
