It can be done..I have a 10 foot Noorduyn Norseman seaplane, about 40 lbs..Flies with a G62 using a 24-8 Zinger prop..Loooong takeoff run off the water, but flies "scale" once in the air....Flies pretty good as a land plane with wheels, with a Zinger 22-10..Loops, rolls, stall turns, things a Norseman probably never does in real life...
