Hello does anyone have ideas why i have an uncharacteristic whistling sound when I back off on the throttle on my new GepRC Smart 3-5?
I confirmed that the motors were snug as well as the propellers.
I also tried swapping out the propellers. The motors are cool to the touch after flying.
I wonder if it's a speed controller issue or a possible PID tune issue? Other than that the quad flies great.
Any ideas?
