Re: Prop size for 4-107
When I try and push the engine above 1800, it starts to smoke a little and then the temperature starts to climb. Not necessarily to overheat, just higher. I usually will do that only if I need to get more speed for a short distance, like trying to make a drawbridge are something. But, for the most part the engine likes running at 1800. If I change the prop to get higher rpms will that effect the engine now that it has gotten use to operating at the speed it does?
