Sorry for misunderstanding.
I meant to say that everything is correct, except phrase about Saito being better.
I personally prefer YS.
IMHO YS has better throttle response then Saito.
But it is really personnel preference. Both are great engines.
I like Saito it is lightweight, swings big prop, and pulls great. But every time when I switch from plane with Saito to the plane with YS...It feels more responsive.
I'd rather have better throttle response then swing slower bigger prop.
But then again it depends on particular plane set up. Some planes will 3D better with the biggest prop you can get on them, but it is not true for every plane.
