RE: RCGF Engines
Well after numerous test of different props, I'm settling on an 18x8. It has the best thrust at an appropriate rpm.
Close to 10lbs of thrust @ 7050rpm's. 87 octane with 40-1 synthetic oil. I'll keep it that way till I feel it's completely broke inthen go to 90 oct with 50-1 synthetic. Love this engine!
