With older designed motors, operating temperature was interesting because the models often
overheated. The current design G231/G26 motors cool very well. Measurement isn’t really
necessary anymore.
However if you insist, normal is gong to be hard to define because the measuring devices are
typically inaccurate and it will depend on exactly where the reading is taken as to whether or
not they will match any other reading. Always use the same measuring device and always
measure in the exact same place on the motor.
In general terms, when measured on the cylinder head, on the exhaust side, two fins above
the exhaust port, the model will hover at a head temp of around 275 degrees Fahrenheit and
normal full power operation will be around 350 degrees Fahrenheit. Your readings may be
different depending on a lot of variables.
The actual number is less important than its relative reading. If it always hovers at 275
degrees and on the next flight it’s running at 375 degrees, then something has changed that
you might want to look into.
