By the time I get to 80" I am courting gasoline and not glow fuel.
Do you want scale, sport-scale, sport or just something that lands on water?
If I were building from plans for an 80" floatplane I'd be checking out a PC-6 Porter. I've been flying a 50" version (on floats) and it would make a wonderful gian scale project.
