Wood size when enlarging the plane.
I want to enlarge twice the span of sport plane for which I have the plans. The current span is 1700mm about 67 inch. I want to make it 134 inch.This is a sport plane polish RWD- 5 construction similar to Piper Cub. Is the any rule about proper wood size, stringer cross section, spars, plywood thickness etc. I should follow?

RE: Wood size when enlarging the plane.
I have gone this route with plans.
The best advice I can give you is two fold:
1. Measure the wood size on the plan to see what sizes you will need.
2. Then use common sense.
You change the size to a readily avilable size. For instance, If a piece of balsa measures out to be 9/64" x 13/64" I would use 1/8 x 1/4, if the ribs measure out to be 3/16" thick, common sense says use 1/8" or 3/32" thick balsa. Same with the firewall - it measures out to 3/4" - depending on engine you use, you would only need 3/8" - 1/2"
