RE: Moki 210
When I bought this engine directly form Mr. Patrick himself whilee at the Ontario, Ca. model show, Mr. Patrick, at that time had no idea as to what fuel, horsepower, prop,ect, to run this engine. It did not even come with instructions or paper work of any kind.
So I concluded............. same engine that can handle no more than 5% nitro. Nitro basically advances the "spark" according to one of rc magazines.
Nothing personal, just an observation
