Sig vs. Midwest Citabria
One of the best and most fun airplanes I've ever had was the Sig Citabria, in the looks department is top notch, and flies like a dream, had mine powered with a ST .51 and it was perfect so the Saito .72 should be right on the money, I also flew mine off water, easy build, but it does however have many parts, mine was covered with supercoverite and painted with automotive enamel, a great little airplane. (very aerobatic too!!)
