Default RE: Need YS guru help

most guys I know run either of these 3.......

20/20 cool power (sometimes called YS)
20/20 power master (sometimes called YS)
30% heli cool power

No one I know runs straight 20% or runs 4 stroke fuel. 20/20 is something different than 4 stroke fuel.

I run my YS63 on 20/20 and my YS140L's on 30%
