Flyin' King on pontoons.  Here is what Dave, from Washington State, has to say about his FK:

Here's a few pics of my flying king, it's on floats in these shots.  I had a satio 91 on it in the beginning, while on wheels, but after adding the extra weight of the floats the satio 91 was very sluggish.

It is now powered by an os91fx, and does very good off the water & in the air. I built the floats to be an easy & quick change back to wheels.

A fun & very relaxing bird to fly.
