Good Morning,
To those of you that have used a Saito 40. What would be the plane size range in sq in to be powered by a saito 40 ?
Thanks

I have used the Saito FA-40 on a Brodak P40 ARF (53" wing, 560 sqin, 55 oz). On my P40, I use an APC 11-6 sport prop at 9,200 rpm on the ground (about 300 rpm below peak to keep it slightly rich). And I run VP 15% AIR fuel, with a little Klotz KL-198 lite syn added to boost the total oil from 18% to 20%.

And seen a Saito 40 on a profile Pathfinder (55" wing, 620 sqin, not sure of the model weight), and also an OS 40 Surpass on a TF Doctor.
