To Hydro Junkie-- I built a Kadet MkII and added one more bay to each wing, and took out over half the dihedral, and it flew like it never wanted to land, it would float forever. Adding the wing area will probably be good, keep the wing loading down a bit with the weight addition from floats. I never flew my Kadet on water but it handled very sweet in the air, less a trainer and more a sport plane with the decreased dihedral, but still not a fast plane. Could climb like a homesick angel with a .46.
