Hi guys;
I've my pattern plane grounded since on the last flight during an push throttle the motor made a kind of screaming sound...
Open the cowl upon the suggestion that an adhesive was touching the motor's fix columns but was not that...
What could it be then?!?!?
The noise comes out only at >60% power; below that everything seems/sounds normal. No extra heat neither...
I'm clueless!!!!!

Note: motor is has only made 25 flighs so far... so it's practically new. This is it: https://www.lindinger.at/en/airplane...rushless-motor

-Thanks on advance;
