RE: OS Max 55 AX issues
Why are you taking temperature readings? This is something that the car guys do! Temperature is not something most airplane guys check!!! We check to see if it is lean or rich! Do the pinch test? does it die? or does it increase in RPM? this is at wide open throttle.
Are you running it with the cowl on or off?
What size prop are you using? IS the motor dying? Does it quit running at anytime when you are giving it throttle?
Please provide more information
