Those "Ugly" SPAD Correx planes can be made in an evening. Some I've seen look better than many balsa things I've seen covered in film.

You can make an aerofoil blade (wing) in tens of minutes. The correx is folded in half over a wooden yard stick ~ SPAR. I don't think they would require any addtional weight as the material is heavier than Balsa. Normally the Planes end up lighter as they don't require any framework (ribs, logerons etc).

There is frequently a lot going on on the SPAD Forum:
