RE: What size prop?
what kind of plane is this going on ? what would be the finish weight of your model or the wing loading ? typically a 46 to 55 size engine will take a 10x6 ,7 to 11x6.7 try a few diffrent ones play around with the pitch and see wich one preforms to your likeing

And 5% nitro fuel. Istill have several of these Russian woders and after fighting with them for a long time it hit me like a thunder bolt. Nitro is a high dollar item over seas and these engines are design for what they can get in Russia. These are very high compression engines and were designed for FAI fuel. You can shim the head to lower the compression or lower the nitro, they run pretty good on 5%, Inever tried FAI but I'm told they run even better with no nitro, just the alcohol and 20% castor oil.
Istill have the 58s and 68s under the bench, when they ran they were great, when they didn't run it was an operator problem, me not understanding the problem.
