I'm on my second seamaster. I will probably always have one of these airplanes. I fly it only off of water. I have plenty of other land airplanes.
I think that the seamaster is one of the best flying planes out there. Having those floats out there on the wing tips act as anti-stall devises. i can really slow this thing down for a landing and it wont tip stall. I can come in really slow, get about 3 inches off the water, give full up elevator and drag the tail in the water. Then increase throttle and accelerate, climb out ,go around a do it again. tons of fun

Flying off of water is easier than land when using the seamaster. It tracks straight for landing and take-offs. I dont use the runner they say to glue on the bottom. Without the runner you can do some really neat brodies and power slides on the water.
I glued a very thin piece if aluminum across the whole the bottom of the plane to protect it from ding and scratches from rocks and such. I usually just power up as i head for the beach and the plane glide up about 4 feet onto shore.
Once this plane is in the air it flies like a sport plane. There are no floats or landing gear hanging from the plane , so its a fairly clean.
Some float planes with those big ole floats hanging from them came be a little combersome in the air, some of those plane are limited to just kind of flying around easy like. But with the seamaster you can fly the way you want- all crazy like me : )
