Hi Anto
The TR control system of the 22 is entirely push-pull rods, from the pedals all the way to the spider.
Inputs by the pilot are transmitted via a bell crank at the rear of the tail boom to the non-rotating portion of the TR pitch controller, which is attached to the rotating part in a similar manner to that of a swashplate for the MRH.
The rotating part has two pitch horns and pitch change links attached to the TRB, collectively changing their pitch to provide directional control about the normal axis.
