Thanks, you are correct: the RJX head does not have a mechanical adjustment for this. I do have what I need to do this on the PC for the BeastX, though, so I will explore it.

Good Day

I am working on a project which involves developing the mixing algorithm for a single rotor (5 bladed) helicopter. I dont have much experience with rotoray wing aircraft and have spent the last few days getting aquainted with the various control characteristics pertinent to such aircraft.

In particular I need to obtain the relationships between control inputs (i.e. collective & cyclic) and the actuator displacements which are attached to the lower non-rotating swash plate such that the rotor blades are pitched by the correct amount. This is necessary to fully understand the process. Additionally, the second objective is to develope a technique for reducing cross-coupling between inputs. Essentially, the goal is to determine the mathematical relation/s which would allow me to develope the algorithm and simulate the system using Matlabs Simulink addon.

Could anyone kindly assist by referring me to appropriate references or point me in a the correct direction to tackle this problem.

Many Thanks in advance
