Hey, another set of "tail dragger" floats. I see yours have a step. I cut mine off at the step, using only the forward portion. They seem to work pretty well. The plane picks its tail up quickly. Admittedly, it is a fun fly plane that is very light, even with the floats, and with a TT .46, it gets off right now.

I have yet to see any downside from these floats. I imagine on a full scale, you'd want the fuselage to sit level to see on the water and for passenger entry, etc.
