the ailerons were way too small, my wheel pants looked like they had been in a furnace, the cowling was a different color red than the fuselage and did not fit right, the line drawn on which the center of your engine is supposed to be was an inch and a half off, my landing gear cracked after 6 landings (fairly smooth) the wheels were crap, you can't put much deflection on the already too small ailerons, all the colors were way off on the recovering kit, the clevises were impossible to thread, there were what looked like tire marks on the side of the plane, but were actually smeared ink, the cradle tape you supply eats the covering on the wing and leaves pieces stuck to it. in short, i would have chucked it and got another but time and money did not permit. also, a lot of the things wrong with it did not show up until i was already building.
