RE: The littlest Saito
I should say that it is Bill's special black cylinder that makes it run so well. I ran mine at the 11,111 rpm you see for a full five minutes, I timed it and it ran very steady no wandering up and down. I don't know if Saito designed it that way but the muffler sounds like a much larger engine.
Ross. mine is headed for a Sig LT 25 kit I built with a nose gear and bolt on wing.
