Regarding the motor, I just liked the idea of having a 1.25 size gasser. I might throw an OS 1.20 2 stroke in it. Still don't have my mind made up. The kit calls for a .90 to 1.20 four stroke so I was thinking the 1.25 gasser would be a good fit, Saito said it would be about 5% less power than the 1.25 glow motor which would be plenty (I think). This isn't a 3D plane, it's scale, with scale size control surfaces. More like a pattern plane.
