I am new to glow fuel RC flight, but I have a lot of experience with nitro RC trucks.

I was wondering, what kind of temperatures do you typically want to see out of an aircraft engine.

I have a Nextstar with an O.S. .46 FXi and it doesn't want to go over 150 F. With nitro RC cars we generally try to keep the running temps over 200F at all times to prevent excessive wear to the engine. Is this also a concern with the plane engines? If so, what are the minimum suggested temps.

I am really concerned, as this engine came with a HSN limiter on it that only allows you to adjust it so far, and according to the manual you aren't supposed to need to adjust it outside of the range the limiter restricts it to. However, I have found that even leaning it as far as the limiter would let me left the engine blubbery rich and it doesn't want to spin up smoothly. I had to remove the limiter and lean it out almost 3/4 of a turn further that the limiter was allowing just to get it running reasonably well and even then the temps would barely go over 160F. The only way I could get it up over 200 was by wrapping the head in a rag to restrict airflow.

Should I be worried about keeping the temps up or do you guys all run the airplane engines really cold?

Thanks.
