I Googled the plane and took the liberty of attaching a picture of it. Very cool looking bird! While my biggest heli is only a 500 maybe something in the .60-.90 size tail rotor would be a closer size for you but the mechanics of grafting something like that onto a motor/shaft AND make it all fit inside a nacelle could be daunting. Even using a smaller main rotor head setup would be difficult. Hey, maybe it's possible. If you can make it happen I'm going to be following every step of the way! It would be fun to have just for the coolness factor!
