I too fly a GP60 90" wing Cub with a Saito 91. Plenty of power. Mostly fly at about 1/3 throttle. I bought this one already built but have a kit on the shelf waiting for time to build. I also have floats for it but they are not completed yet. Maybe ready for use on snow this winter and then the lakes next summer.

This is an easy to fly model as long as you respect the wind direction. I got caught once by a crosswind on a touch and go. Turned into a touch and flip. Minor damage and back in the air now.

And I fly 15 minute flights on less than half a tank.
