UniCopter ~ Control - Flight - Sidearm Controller
A loose collection of information.
Comanche utilizes a limited displacement, unique trim. 3 axis sidearm controller and has no tail rotor pedals.
Picture and some information in [Source ~ RWP3 p.50] Vertical pull changes collective pitch, rotation changes yaw and tilting changes longitudinal and lateral cyclic.

If OTHER: Rotor Concept - Electrical Twisting of Spar is to be implemented, then the sidearm controller becomes quite feasible. The sidearm controller will eliminate; the central cyclic stick, the need for the SynchroLite's 'control rod tunnel', and may eliminate the collective lever and the pedals. I.e. all flight-controls in one hand and the other hand is free. In addition, there are fewer restrictions to ingress to and egress from the cockpit. In addition, the mixer box can be all electronic.
It is also under serious consideration for the Single-Bladed All Electric Rotor.
