I am flying an Uproar on floats. The Uproar is about the same plane as the Dazzler without the turtledeck and with the goofy shaped ailerons. Mine doesn't have them. I am using Plane Fun foam floats and U-Can-Do landing gear for struts. I added a 1/4 ply plate behind the wing for the rear strut mount.

The spreaders are black, fiberglass pushrods I had.

Power is a Saito .56 with a 12-6 prop. You shouldn't need a .75 as the Dazzler and Uproar are pretty light to begin with.

I did add a small sub fin as many of my seaplanes need a little added fin area after the floats have been added.

I am using an Ernst water rudder I ordered from Tower. The servo is in the fuaelage with a Sullivan cable pushrod running down to it.

Your Dazzler will be a great flying seaplane with any .46-.55 in it.
