RE: New Saito 4 Cycle Gas Engine, 3 Cyl FG-84
So in the end.. Meth is more powerful and more expensive. You need larger fuel tanks to fly the same amount of time. Not making a judgement here, just pointing the salient differences between the two.
My bud has a Saito 450 in his #36lb Wildcat. It flys the plane but yes it could use more power. Maybe he should consider CDI for the plane.. i know from experience that 200-300 rps with his plane can make a big difference.
