The Cardboard Airplane

I am building a cardboard airplane. I wonder if this is the way the Wright Brothers started out? As I may have mentioned, a Teenie Two built exactly to plans is a little too snug for me. It's not necessarily a bad thing because I suspect being strapped into that tight cockpit gives one a sense of being truly part of the airplane. I am thinking that I will like flying the airplane a little too much and a larger cockpit will allow me to enjoy longer flights in it.

So rather than jump into cutting metal, I decided I would build a mock-up of the airplane to see where the dimensions might be enlarged. The seat back, the widest point of the Teenie's fuselage is 21 inches when built to plans. I am stretching that to 23 inches. The instrument panel a.k.a. bulkhead B, will be 22 inches wide with a height yet to be determined.

I also need to determine the width of the firewall, bulkhead A, and the two rear bulkheads, C and D. It is my intention to leave them as they are in the plans to avoid more changes if I can.
