The Tail Mechanism was going to be working but my lack in metal working skill and cash meant it was 3D Printed on my brothers printer and tuned out not to be strong enough to lift the tail. I've not given up on the idea.
I wasn't running it when the video was taken as I would have spun it round to show the other sponson; the barrels have a Sub Leveler on them so that they twitch and stay level as if someone was operating them, unfortunately the right hand barrel came loose on the day and couldn't do anything about it.
