If you are using 30% nitro use the APC 16 x 4W and if you use 20% or less then use the 15 x 4W. For folks running the YS 91 then the 16 x 4W works good.

Ed, I have thought of this alternative. Will the 30% be enough to compensate for the sluggish performance with the Saito 100 and a 16/4? Also will the low end have to be reset to compensate for the higher nitro content and the additional oil? Thanks, Joe
