Planetheli : Yes, i could figure that you had to run it rich in the tropics. In the summer I have to do the same.
WE had a hot summer yes. We usually do in the south. today it is 25 C.
NO watercooled heliengines here. It was just a joke directed to the replies above, but it would be fun though...
Have a nice day.

A water cooled RC heli engine is not as daft as it seems maybe.
You've only got to look at the evolution of small motorcycle engines over the last 2 or 3 decades. And then. it was only a few years ago that no-one would have dreamed of having water flowing through your PC to cool the CPU, then it was only the nerds, now it is quite commonplace. With the right facilities, it wouldn't be too difficult to experiment.
With more consistent cooling, it should be possible to wring more power out of the engine. Whether this would be be enough to offset the weight penalty is another matter.
Does anyone know if marine RC engines use different piston / cylinder clearances or do they just bolt a water cooled head on and leave it at that?
