I also think that if you have something like an OS .40 you probably need to up size a tick. I have an Avistar with that engine and she could barely break away from the water. I went to an os .46 and it was like a whole new plane!
I converted a Easyfly2 to a float plane and I could barely get it off the water. I'm going to try a .46 engine.
