RE: Phencepost
Fiberglassed the whole thing in 1.5 oz fiberglass with the center 18" getting two layers. I used EZ-Lam from aerospace composite products (on the web). Must use epoxy resin polyester resins will melt the foam. If your resin has a powerful stink it is going to melt your wing. Get some laminating resin or sometimes called epoxy finish resin. It is thinner and easier to apply and scrape off. The fiberglass gives a smoother finish for better aerodynamics, a stiffer stronger wing and I think a lighter wing compared to bi directional tape. However its impact resistance is less, the glass and epoxy does not give much. The bi di tape wing oftens survives dirt naps and mid airs by giving a little. Just a matter of preference, most people tape their wings. I run two flights on my little 370 mah pack. I think I'll slap it into cycler at see what is left after two flights. Let you know tommorrow if a third flight was left in the pack.
