Default RE: O.S. engine issue
I am running my O.S. .46 AX on an 11X6 prop. At peak RPM I am hitting 13,300. I then richen it up to 12, 900 (or maybe just a little bit lower). The only problem I have had with it is once, it two hits of the electric starter to get it to catch. Also, I am running 15% nitromethane with 20% all castor oil. I love the engine.
