I added floats to my Great Planes Easy Sport 40. It was underpowered and overweight(lots of epoxy from repairs)with a LA.46. After trying a couple different size Saito's, I finally stayed with the OSFX91 I mounted. This plane is now overpowered and it screams at full throttle! It get's up on step quickly and is airborne immediatly. I'm at a very high altitude (over 6000ft.) so the extra power is nice to have.
