Hey Allan.
I wasnt even aware you had this product in your line up. Just watched the video. Great.
As an avid flyer I have left my plane out at many fbos across US and Canada and had some sleepless nights as the winds howled. I have the pvc rudder lock, a bunch of tin with rubber hose locks and some airgizmo locks. Several times the airgizmos have worked loose and not done their job. When I read of other rvers having rudder damage etc, I just shudder. What a shame.
I like your solution. Might just have to order one. Good luck, keep making some good stuff. Enjoy your video style...fun watch with a coffee.
