Good stuff!!!
I took pencil to paper and tried to remember my trigonometry. ..
If I am correct I can go 10.5 inches into wing using 1" o.d.tube, but spares are 3/4 wide..will this mean I must use 3/4 tube?
I have 1.575 between top and bottom spar.
I want 2.5 Deg dihedral each side.
I will redo my calculations for a 3/4 tube to check how long tube must be.
next question....how thick tube wall needs to be?
