One issue that has not been addressed here is that more float is not always better. If a float is too long the aircraft can't rotate. One test is to set the plane on a table. with the wing incedence at zero push the tail down as far as the floats will allow. If you can't get at least a +7 degree incenence as measured at the wing the floats are too long or not properly mounted.

I set mine up with 1 or 2 degree positive wing when the float is level .

Last of all 86 the GEE BEE floats. I have been float flying for 30 years and have seen only very light overpowered planes work with these floats. They look like a quick and easy way to get into float flying, but there are several problems with their basic design, the step being the biggest. The rounded edges on the bottom of the float are also a problem, that edge should be sharp. I learned this the hard way too!
