Evolution of Design
I have been keeping a record of the Evolution of the Design. You can read the process in the R&D section and see some photos below of the 1st, 2nd, 3rd & 4th prototype.
Fourth prototype - A number of changes including a pre-cut spar channel. Only 800 grams compared to the 3rd prototype but of equal strength. Read the R&D
Third prototype - Modified build to make a firmer wing. (50 inches, 977 grams). Read the R&D.
