thanks for posting. here are some of the things you Should have understood, BEFORE making use of PLANS. at :07, it appears that a ZERO-lift, symmetrical profile is used in the design of the main wing. this is fine, ONLY, at The Wing ROOT. ( aha. :29. good. oops, spoke too soon.) at :48, the profile of the ribs LOOKs Symmetrical, to me. in the days of gas-power, it was Common to use a symmetrical airfoil, and a wing mounted at a POSITIVE aoi. this, however, is an energy INEFFICIENT way to make lift. at :12, compare the use of full-length (side) panel fuselage construction; including cutouts 'between' formers. see linked photo. at 3:34, the aft tail boom is FAT. in part, because servos are THERE. servos Should Be installed 'near' the CG. at 5:00, (weight-reducing) CUTOUTS Should have been used, between fuselage formers and at the 'solid panel' stabs. longitudinal joins of panels RESULT in strength. transverse formers (and joins) control wracking, of a built-up fuselage. cheers googletranslate cutouts www.modelairplanenews.com/wp-content/uploads/2013/03/3-Fuse-Framed-rearview-web.jpg www.picclickimg.com/00/s/NjYyWDE1MDU=/z/rRgAAOSwGvhT63Rq/$/1-3-Scale-128-inch-Super-Decathlon-_57.jpg
yes I have a short one of the first take off nut I will try to make a new one next time that I fly. the engine initial was a crrc 50cc but now I changed it with a us 41cc
