I have a complete set of used fiberglass wing, elevator and rudder tips as well as the dorsal fin. they are all in need of minor repair. If you or someone you know is good with fiberglass, they should be an easy fix. New set cost over $1000.00 from Stene Aviation Inc. $1321.62 to be exact. I would sell them all for $50.00 plus shipping.
Fiberglass is so durable and easy to work with and repair, why do you want to sell the stuff?
