I'm learning

**Grasshopper**for Rhino, it's a procedural modeling add-on (free!). As my first project, I'm developing an airplane design software for my model planes

*but*I'm also setting it up to be useful for full-scale builders and designers as well.

Right now all I have is a single wing. I hope to add the ability for users to add weights, tails, multiple wings and more. You can check it out

**by clicking here**.

Some feedback I need help with right away is: how can I account for wing sweep with total lift of a wing? I see "lift decreases by the cosine of the angle" but I don't know how to integrate that cosine into the lift equation. Any help would be appreciated - thank you!
