Whistle
My RV-9A has a distinct scream or whistle, in videos it sounds great. I could send you one via email if you would like.
My neighbors know its me flying over without even having to look up.

Whistle
The sound is created by airflow over the bottom of the h.s. and the elevator at the hinge openings. It only occurs on some aircraft but is related to traffic pattern speeds when the nose is trimmed up/trailing edge of elevator up. Mine made the whistle and I tried covering various openings on the tail with sail plane tape. When the hinge openings on the bottom of the elevator were covered the noise went away--removed the tape and the noise returned.
Cheers,

An age-restricted video. They want me to "sign in" to open it.
Like no way!

My bad.....First time I've uploaded. I was just clicking all the buttons! Now sorted!
Hey, I want mine to sound like that!!
Do you/we gain the requisite coolness-factor 3-5kts of speed per dB of whistle, like painting your wings or tail checkerboard does?
Unfortunately the RV-9 does not qualify for "checkerboard". Checkerboard denotes "Aerobatic" and the RV-9 is not aerobatic.
The "whistle" may be enhanced by painting the aircraft dark blue like the F4U Corsair! No guarantees!
Whistle in Cockpit
My RV9A whistles at about 125kts and is very apparent in the cockpit. Some of the RV guy's think it's the front left edge of the tip up canopy as it is not perfectly flush in that spot. Open to ideas, reseal? The plane is new to me so working through things.
