I have a NIB Fox 15 CL engine. Am planning to start initial break-in on my test stand. My question relates to the best fuel to use. The reading I have done just says it works best on 'Missile Mist' fuel. Missile mist as I understand it is 25% nitro / 18% castor. To me the oil content seems low for the engine metallurgy, and the nitro seems a bit high.
Could the experts out there please recommend the best fuel makeup to use. I do have some 15% & 25% nitro fuels, both 23% total oil (50/50 castor/syn). And have castor that I can also add. I want to use a fuel that has a good balance between power and engine longevity.
Thanks in advance.
