Wing
The first wings will have a 50 inch span. They will be made from fiberglass, Kevlar, epoxy and foam. We will be using a vacuum bagging system to hold it together while the epoxy cures.
The Wings will have a 7-1/2 inch root cord and a 4-1/2 inch tip cord. This will give us a wing area of about 300 square inchs.
The wings will have full span ailerons with a servo for each. |
