RE: 2 Stroke vs. 4 Stroke
There's no dispute that YS 4-strokes produce best-in-class power for any given engine size, but to get that power you have to use high nitro fuel (20% ormore)andthe costcan start to add up.
I'm kinda like Gray Beard. I like the 2-strokes that can turn large props. My personal preference is for Webra's. Nitro in Europe is expensive so engines made there typically peform really well on very little nitro.
I have a Webra .91 2-strokethat runs extremely welland effortlessly turns a 15x8 prop in the mid 9's. Remember, this is on FAI fuel or 5% nitro so my fuel costs are considerably cheaper. The OS equivelent can't even reach those rpms on 15% fuel.
Can any tell me what a YS 1.10 turns15x8, 16x6 and16x6 props at?
