Frank, No..... it's a 33cc gasoline engine that performs better than any other 30cc class engine andfairly close tosome of the 50cc engines. My main point is that any current legal airframe can be set-up with it and it will perform as well as the best electrics and the YS170-175 glow fuel powered models.

Of couse if your heart is set on the larger plane, different story. The OS will do fine there too but would be so tail heavy that it would be impractical. You'd need a pound of nose weight to balance.

If you decide to go with the larger model, let me suggest a DLE55, ESComposites 55G pipe, Merle's or my soft mount, and a Mezjlik 20x12 3 bladed carbon prop. Lots of power and electric like quiet. I have one of my current models equipped that way. It's a terrific combo
