This is the best prop I've seen:

This one might be good too:

Maybe you should try some kind of catapult system like the Wright brothers
used?
As for the motor - I'm not sure what you could use. I've connected the Set
#5113 Airscrew to a motor before and wasn't impressed with the thrust
generated. You'd need a lot more RPM to overcome the weight of the motor.
The 3 Blade 9 Diameter motor is fairly light though, and could possibly be
powered by a rubber band.
You might also consider mounting a CO2 cartridge to the underside of your
gliders nose. Hobby shops, bicycle shops, and sporting goods stores should
have them in various sizes/weights.
