Heres the video of my maiden today i figured the whistling sound may be the air going through the fuselage but im not sure. Any suggestions? It doesnt do it on the ground. I throttled up and took it high, cut the power and let it drop with no power and it still whistles. Could it be the wind through the wingstruts? Wheel fearings? Cowling? Any suggestions?
