Thanks for the reply Horace. I'm not really concerned about the weight of this plane. From my understanding is that it is designed that way, ie.. a fully sheeted fuse and fully sheeted foam core wings. The YS I have bought is the first one I have owned but from doing research I have heard that it pulls as good as most 120 to 140 sized four strokes. I'm looking at using this plane for Sport and IMAC type flying so the wieght won't be too much of a consideration, as this plane was not designed for 3d type flying.
