Put at least 2" (50mm) of dihedral under each wing tip before test gliding.

To prevent further damage to your foam fuselage, you can:
1. Stop gliding the airplane Shocked
2. Build another fuselage out of wood
3. Coat the foam nose with epoxy... not fiberglass resin (which attacks and destroys foam.)

There is an old trick I learned from one of our ancients (he is still flying indoor classes at the age of 87 Cool).

The trick is how to bend bamboo over a candle flame.

Use a suitable length of bamboo (a kebab stick about 3mm diameter would be a good start). Shave down to about 1.5mmx3mm and then bend to (roughly) the shape of the lower profile of the fuselage. It does not need to go any further back than the le of the wing, so it will also count toward the nose ballast required.

Glue it on with your slow adhesive.

If you can get hold of a piece of sheet galv steel (about .3mm or so guage) bend it to a 'U' shape and put that over the candle as an anvil. Bend the bamboo by wetting the inside surface (spit is useful!!) and then run it slowly over the hot metal (or over, not through, the candle flame). Takes a bit of practice but it works.
