It seemed to fly really well- and much faster than I expected. Unfortunately between the gusty wings and one of the elevon clevises coming loose, I had multiple hard impacts straight into the ground. The foam eventually tore right at one of the 90 degree corners in the propeller pocket. I kept on flying it after repairing the tear with tape. But, by this point it was pretty dented up from multiple hard impacts and wasn't flying very well. So I kept on flying it until the motor mount tore out and wasn't repairable with packing tape. I suppose that is the big advantage of really cheap, easy to make airplanes.
I'm definitely going to build another, but with some slight changes:
- curved corners in the propeller pocket to eliminate that stress concentration / tear point
- Sand / cut the trailing edge thinner before I fold it over, to make the completed, folded wing trailing edge thinner and closer to the thickness of the elevon
- Make a more durable motor mount
- mount the ESC / receiver in the wing before folding to reduce the amount of cutting required to the outside skin & foam main spar
