BARRY
I wrote previously, but with the two pictures included, I couldn't get it past my browser.
I have an O.S. .91 4 cycle pumper and an APC 14-6 prop. I have tried the C.G. in several places. I have weighed the tail down so in an inverted flat spin the nose was pointed up at about a 20 degree angle and still wouldn't climb. I agree that I need more power for a climbing spin.

If anyone reading this is interested in float flying with a .46, I used Goldberg "Super Floats" which adds 2 pounds to the flying weight which is why I used the .91 engine, and the C.G. is at 6 inches. The struts are Dubro plastic gear which is flexible and much better than rigid aluminum for flying where there is turbulance from waves and wake from jet skiis and boats. With the pontoons, the plane spins as flat as a saucer. Comes out of the spin immediately with neutral rudder. High rate on the ailerons is 45 degrees and 60 degrees on the elevator and rudder.

There is nothing prettier than a smooth landing on calm water.

Beautiful to watch. Exciting to execute.
