I am wanting to do trike gear and wing mounted. I want it to ba a large version of a 60 size.I have a idea of how I want to do the mounts for the gear in my head but i want to iron out the rest of the wing first.. Is weight going to be that big of a issue. Im not wanting to build heavy but i dont want a plane that is floaty. I like the idea of the 48" carbon spars. Im just not sure if I can designa rib with a carbon spar with out the balsa.
