I built an enlarged modified version of a Spad called a Demon. It had a 66" span and was a fast flyer and handled the wind well with an Os 46FX on the front. The wings tend to be very heavy but tough as nails while the fuselage is very light. I ploughed into the side of a hill once with it and took out a bunch of weeds and some scrub grass. The wing of course was undamaged! I eventually stripped it for parts because of the look of the thing and I didn't like not being able to see the skinny white fuselage in the air. [8D]
