Tail Rotor Shaft size

Hi All,
I am looking into building a multi-rotor using 450 main rotors but since I do not need cyclic I wanted to substitute a tail rotor pitch control for the swashplate. The 450 main shaft is 5mm, does anyone know which helicopters use a 5mm tail rotor shaft?
I tried posting this on the VTOL forum but is seems they all use propellers, not rotors.

I do know that the original Synergy N5 used a 5mm tail shaft. They were later upgraded to 6mm but the 5mm hardware is still available.

Thanks, I will check into it. I found the Trex 600 manual lists part sizes and it uses a 5mm tail rotor shaft also.
