Gents,
Some pictures about engine temperature.

A new thermocouple for the Top Flite Taurus engine. Important part of electronics is the + 200 degrees Celsius detector to see if on any moment during the flight the engine head temp was above 200 degrees.
When I did run the OS Max 61 FX it did happen twice! Guess why? See picture 2 and see the carburetor!

I also can take tempreature samples during flight with a datalogger.

For the gasser I did read, the temps are the same see this post:
