Excellent link dvt, a must read for everyone. As can be seen from the bulletin, the sideslip maneuver produces no unusual stresses on the tail whatsoever.
With that, I now stow my ‘resident test pilot’ wings safely in my desk drawer, and go out to drone along the night skies secure in the knowledge that if something is going to break, it’s not likely to be the fin. Anyone out there who wants to give multiple full rudder reversals a go, please make sure someone on the ground has a video camera.
