That looks like an elevator on an aircraft. Another question while im here, are you able to get any good pictures of a piper malibu piston? Im thinking of building one for Microsoft flight simulator.
It almost looks like a skid and rear end of a Chopper ( I have no idea what sort though)
No : Sorry both erronuous. It is not a rotary machine, nor is it at the back end.PD :- I haven't found a really good shot of a Malibu yet. Still rummaging tho.
