I've been working on a new wing. The price of tooling is a killer!

It's tested and I'm very happy with the results, just think about what might be the most effective version and what to put our efforts into if at all. All designed in Rhino CAD and Solid Works so mods are no problem.

We have two build options a carbon fiber/glass version and foam version. 2 Factories have expressed interest.
