What is the normal operating temperature for glow engines? I am sure this varies from engine to engine based on size and mounting dynamics (cowels). I am running two O.S. .91FX two stroke engines in my tightly coweled P-38 and was wondering about cooling. Over 65 flight so far but I had an engine out a few weeks ago and it got me thinking. What is too hot? The engines are generally in the 165-200 degrees Fahrenheit range after a flight. Is this acceptable?
Thanks!!
