I have an 80" Hangar 9 Cub that I may want to put floats on but then again.....what are some other high wingers that will lift off slow and look great while flying on floats?

It's hard to beat a Kadet Senior on floats
Seaplane

If you like to build, the PT 60 with Great Planes 40 floats works very good for me.
I like to add the reason for the 40 floats, mine are built up and completely glassed which adds weight but are very strong. Also I powered my PT 60 with the new OS 70 4 stroke and using a 3 blade prop. I would recommend a strong 60 2 cycle or a 82 4 stroke. Also reason for the three blade is to keep it out of the water on take off. Another change I would have done if doing it over is make sure I had a little more clearence between the engine and water so I could use a 2 blade prop which I believe would be better for my 70.

Last year our club put together a SIG Kadet LT-40 ARF with an OS 46AX and Great Planes Fiberglass ARF Sport Floats. We use this plane to train the area kids how to fly off a local lake and also use it to give kids a flight during our float fly, which by the way, is July 14-16 at Lake Selmac, OR.

It's a big easy flying plane and since we used ARF stuff it can be assembled very quickly. The kids think it's great. It flys slow, handles great and even though it's got a 70" wingspan a .46 will fly it just fine. We'll fly it all 3 days on less than a gallon of fuel.

Seaplane hit the nail on the head. A Kadet Senior is probably the ultimate high-wing floatplane. When I was in the Florida Float Flyers in Tampa, there were at least six of them flying...with anything from a .45 2-stroke to a .91 4-stroke. ALL were modified with ailerons, and at least one was an ARF.

I flew a Senior Telemaster with an OS.91, 45" foam-core floats. It would take off in 8 feet, or at 1/4 throttle it made great scale-looking takeoffs.

Floats make trainers with flat-bottom airfoils MORE aerobatic.

All the other trainers mentioned will also work well. We tried a Midwest Aero-star .60 with Goldberg Floats for a club trainer. It came out to 12 pounds. We called it "The Uranium Trainer"-heavier than lead. I don't think it was the Aero-star, but I really try to avoid built-up plywood floats except possibly as baseball bats or to keep my car from rolling off the jack when changing tires. The Aero-star flew, and it was really sluggish at that weight. But it was really pretty, if that matters.

One last possibility would be the BTE Flyin' King. Much like a Kadet Senior, but with a semisymmetrical airfoil for better aerobatics and with flaps. Flaps can really help a seaplane because the steepen the glide and get your approach safely over the trees on the other shore of the pond.

What about a CG Eagle II? I put floats on mine over the winter and I never took them off. It flys great off the water and will do just about anything you would expect from a trainer. Stall turns, Loops, rolls, etc... and it only has a lil'old, inexpensive OS 46LA. Mine is a kit version but it is also sold as an ARF. The floats are Super Flying Models 40 size fiberglass floats.

Another question......what is the BTE Flying King? and is it an ARF? Would like to see one.
Thannks for the replies so far. The Kadet Sr. may be a good one for me.

no its not an ARF it is a kit...
