Default RE: where do i get the size from
I have always used Chuck Cunningham's formula with pretty good success. He reckons the length of the fuse. to be measured from the BACK of the prop to the ELEVATOR hinge line; that is 53.5" on my LT-40 ARF. Multiply by 75% = 40.125".

Mine is powered by a Saito FA-72 [four stroke].

I had a set of 36" Great Planes fiberglass floats on, but were obviously too short. They particularly needed to extend furthar in front of the prop. Keep in mind, I run a 13" dia. prop, so the mounting gear is a little taller.
