Nony - If I need more positive incidence as JohnBuckner points out, wouldn't I be increasing the distance between the tail and the floats?
nope..the wing would have a positive angle relative to the floats which would put it slightly nose high / tail low while sitting in the water......
If the cub weighs any more than 10 or 11 lbs, you are asking too much from a surpass 70...
