RE: Sig SE on Floats
With an aircraft configuration like the SE, you want about 2 degrees minimum positive incidence between the wing and the front of the floats. Looking at the plane from the side, the front tips of the floats are further away from the fuselage than the back of the floats. I did this on my low wing Cloud Dancer on Goldberg Superfloats and I was in the air in 25 feet with average power. Works great.
