"OS FX .40 , TT.40 PRO SE and SK .40 are also good engines and are very userfriendly, and they all turn the 10x6 RAM and Graupner props at around 13600-13800rpm."
"Sadly FOX .40 engines are no good compared to the above engines."

I don't know what Fox .40 you have used but mine swings a 10X6 at 14,500 RPM on FAI fuel.
