Here are two programs to aid you in float sizing for your
Dual float setup FloatDes.exe
You can download and run them on your
computer, or run them directly from this site.
Each program will
ask you the distance in inches from the propeller to the rudder hinge

THE BASICS OF FLOAT
with contributions from Skip Pothier and
Q and A
1. Where does the step go? Seems best at the
CG or 1/2 to 1 inch behind the CG.
2. What about wing incidence? You should have
the tops of your floats parallel with the center line of the wing.
example, on a flat bottomed wing, make the floats parallel with the bottom
of the wing.
3. How far in front of my propeller do I put the tip of
my floats? About 2 inches in front of the propeller should keep
plane from nosing over when you throttle up.
4. What kind of propeller should I use?
5. Do I have to buy expensive floats? No. You
can make your own with dynamite and nails. Just kidding.
You can make
your own by using a hot wire cutter, and cutting slabs of white foam to
the proper shape.
Then epoxy hardwood into them for gear attachment,
and sheet with balsa, or cover with low temp film.
