hi i have a lot of experience with this engine , after upgrade the engine with some new parts , i think that is the most powerful engine in the market, and the best transition that you could get, but the engine requiere a lot of cares.

first of all you need to get the engine very cold, thats the secret about this engine , i have 2 mintor 170 in a pair of camodel fantasy, runnnig apc 17x12 at 8,300 rpm one os a5 and os typef, 15% nitro 18% oil and aluminium pipe made by 3m , yo can visit my web page www.marcelozini.com.ar and under eventos you can see a vidio of my plane with that engine..

good flight
