Yep...that may have been the culprit. Will definitely keep an out for it.
Flew her again for 6 minutes the other day and the motor definitely was very hot even on a mild day. I am going to enlarge the hole surrounding the plastic motor housing to help increase airflow. I plan to bring out the heat gun to measure the temperature next time just to get an idea. At some point, I may switch motor to EF park 480.

Have you checked the temperature of the motor during a typical run?
Too much heat will melt the glue holding the magnets and / or holding the wire windings and will cause issues!
