There are many different type of Tail Rotor in actual helicopter.
This model is a Rod (push/pull) type Tail Rotor including Tail Gearbox (TGB) and Control Pedal to understand the basic Helicopter Tail Rotor function.
Drag Hinge, Flap Hinge and Cyclic Feathering Function are not necessarily required for Tail Rotor, because of Blades are short and vertical installation etc.

3. Pedal Type Pilot Control mechanism. (Linkage)
4. Input shaft height is matched to TTO shaft height of my MGB model for future use.
