Thanks for all the great info!! I also started around the end of June with a superstar that is still flyable but looks like it's been through the ringer, because it has. I soon found trees and aircraft don't mix well. Anyway my favorite flying is on floats as we are surrounded by lakes. I mounted a set Great Planes floats on a Tower trainer and I was hooked. Since then I added a Ace Seamaster and now would like something a little bigger........maybe the Cessna, it sure looks good. Have you tried it of the water and did you buy it direct from Falcon. I think Quantum or Omni-models have them now. The price is probably the same. I like your idea with the water rudder and making the quick change and would do that even if I planed to leave it on floats permanently.
