I'm thinking about bashing a 4*120 into a biplane. I have a complete wing kit and a set of plans. It will be easy to trace the wing parts and cut them out on a scroll saw. I can scrath the fuse off my old plans. I want to widen the fuse, because the stock 4*120 fuse is very narrow. Hard to get my fat hands inside. Thats a simple mater of increasing the width of the fuse formers.

I will mount the top wing slightly forward of the bottom wing. Both wings will be shortened from 81" to around 72" so that I can get them in my truck.

I am pretty sure that I'll need to change the length of the fuselage. I think it should be extended out a bit to help with stability. I don't want an overly pitchy plane. In stock form, the fuselage is about 65" long. I was planning to lengthen it out to about 71". Again, thats strictly based on my limitations for transport. I'd like it longer, but it still needs to fit in the truck.

There used to be some pictures floating around that showed basic ratios.
I.E. Wingspan:fuselage length --- Cord:wingspan --- Horizontal surface area:wing area

Does anyone know where I can find these ratios? Needs to be bipe specific.

Any other help on the design would be great.
