I fly all 4 of the Falcon planes on floats and they have been a blast for years, in fact I have 2 of the Beavers and plan on getting another Cessna it is super with a 91 4stroke using a 3 bladed prop. Try them, you'll love em. I also have the Jupiter and have thought many times about trying to mount a set of the Falcon floats to it, to lazy I guess as I have the floats already and it hasn't happened yet.
Don't worry about about these planes, just set them up like they say and go ENJOY..
