O.S. 1.60 twin rpm results
Byron 10% nitro 18% oil, APC 17X6 prop, about 65 degrees, 300' elevation 1/2 gallon thru engine, 9000 rpm peaked.
Not too bad, about what I would expect from a Saito 150 or YS 120 on 20% nitro.
I only ran it peaked long enough to get the reading as I'm still breaking it in.
Ran an APC 18X6=7900 rpm.

Shameless bump. This is an excellent engine and would recommend the OS twins to anyone looking to get a two cylinder 4 stroke.
