Yea, I want to add the extra weight..I like small gas engines. They're clean, less expensive to operate , usually require no starter-the small ones or ones with spring starters. But for all those creature comforts you sacriface wing loading...making landings and aerobatics more difficult. I think the 4*120 and 76" Lazy Ace bipe could carry the extra weight OK.

I must admit that 4cy's are my next farorite, love that smell, sound and better power to weight! Life is a such trade off!
