RE: Why not very many tri float designs?
HK4ECG, that Fockker Eindecker looks like it ROW really well and flys very well also. It looked like you were trying to get a wingtip to carve the water at one time in that video.
Charlie P. , those are two very worthy models to build. What I would give to be in an open cockpit like that cruising above the water, although it would be better if it was on my time and not the military's.
