RE: Float Plane info ?
I can tell you that having a set of floats too small for that plane won't work off of the water but work great on snow. I put a set on one of my planes(big high wing Telematser/Kadet type) and they were too short to keep the the plane stable or work at all on the water . They just came flush with the prop nut and they were too short for the rear with the step on the CG. But the plane handled , took-off ,and landed well on powered or packed snow.
You should have no trouble on the snow...just make sure it's balanced ! Floats work great on snow, better than skis for big , heavy planes and you can go out in the deep snow . Using skis on heavy planes I would be limited to 2 inches of new snow or wait until it melted down and iced-up.
If you want to make it into a water float plane you will need a longer set of floats as that's why the tail is falling.
