Eindecker Design Update

My original thought with this design was to use a flat bottom wing with a 1 1/2" wing-tube.
This works fine but I had wanted the wing wires to be non functional. Without any sheeting on the wing there is just to much twist without functional wing wires.
Also the wing tips are not strong enough when a cross wind picks up one side and drives the other tip along the ground.

So a redesign has been done.

1. The new wing is the same overall size.
2. The airfoil has been changed to an under cambered airfoil.
3. 1" wing tube for ease of assembly.
4, Ailerons moved inboard one bay, 5 bays wide and 4" deep instead of 6" deep.
5. One piece wing tip braced back into the wing two ribs.
6. Wing wires are required.

I have completed the drawings for these changes and I have cut the left wing panel.
The new wing build begins today.
