Jim,

The top 3-view is the basic idea. Doesn't the end of the float need to extend out past the prop?

I have an old Heckler 3D. Flaps is swinging some arcs to see where we'll need to mount the retracts. He thinks we'll need 9" legs to clear a 12" prop. Right now I have a GMS .47 on it, but with the extra weight, we might need a .61. We are planning on fixed tip floats at first. This will just be a lash-up to see if the retracts work. Later on, we can make a new plane with retract tips and a better looking fuselage.

As soon as we get building, I'll post pictures.
