I am getting some type of high-pitch vibration sound around 80mph. It can be heard inside the cockpit when the power is pulled back. You can hear it in this video on the outside views, mainly around 1:13. I have heard it on another video, but have had no response from him yet. Any help in identifying where it might be coming from? Don't know if it might be coming from the springs on the cabane gear, maybe the gear leg fairings, or something else, but its definitely loud!
