Designing your own FT-style wings


After building the FT Legacy V2, I find myself extremely interested in the folded style wings. So, I thought about it, drew a few pictures, and built myself a spreadsheet that calculates the spacing of the scribe and reference lines. Looking into the wing assembly of the FT legacy will provide insight into the wings the spreadsheet gives you. the units are agnostic. Just be consistent.

The print range is set to give you a worksheet to take to your building table.

I've created wings from 21 cm chord/6% thick to 40 cm chord/12% thick.
By creatively aligning two sets of information, I've made several tapered wings.

The worksheet is in the zip file.
