I tried float flying once...
Jerry,
I hate to tell you this, but
I built a Great Planes Decathlon (same color scheme btw)with Goldberg floats years ago, it never flew well with the floats
I suspect it was the full symmetrical wing fighting the floats,
That wing needed so much rotation angle that it was always fighting the floats, I could never get it to trim out and if I pulled up or down to quick the floats took over and pitched it up or down violently.
It finially augured in in a death spiral, hit the ground, but actually flew again,,,, without the floats
good luck
