Here is the method I employ.

I picked up a temp gun that has a "MAX TEMP" option. I press this button and pass the gun back and forth over every area of the engine I can hit with it. The gun will then display the highest temp it found.

I do this immediatly after shutting off the engine and then a couple more times after that to see how saturated the engine temp was.

I run a ZDZ 160 Champion and my temps are typically between 180-190 F immediatly after landing. Occasionally on days over 100 degrees I have hit 220 -250 F.

I also check a friends engine. He runs a DA 150 and his temps are right around 120 - 130F immediatly after shutdown, but increases to 140 - 150F in the minutes following shutdown.


I go to great lengths to keep my engine cool since it only take once to heat damage it
