RE: Question building polyhedral wing, and wings in general
So you are saying your single tapered wing ( the leading edge) turns into a double tapered wing ( the leading AND trailing edge)?
I build all four panels flat with a steel rule at the trailing edge to ensure that it is straight. Then the tricky part, sanding and fitting the joints while keeping the TE straight.
I have learned the hard way GO SLOW! a few strokes with the sanding block, check fit, repeat. Might take me all day to fit the poly and dihederal joints but I am usually less than 1/32 off some times less!
BM's way takes all the guess work out of it! A hinged board I am assuming? Sure would like to see pictures. Could be another winter project.....
