RE: What are some of the best running engines in the .40 to .50 rangr?
Enya is very powerful compared to the competition. Half throttle I am passing other 40s in the sky like they are standing still...and they are on full power. BUT they are a PAIN to get started, the needle valves are made to chop your fingers off, and a PAIN to get running reliably...as far as I can tell. Only have experience with the 40ss
