There is feed back from the cyclic and collective controls when either has input, sometimes severe. To understand when either control has input the other generates an unwanted input. Servos have been changed, hydraulic pump & reservoir, filter and bypass as well as the control mixer, rod ends inspected. Next up is the swashplate. Has anyone experienced this issue and corrected it ?

Without knowing what airframe the 'issue' occurs in, I'll say that some feedback, crossing controls is present but minimized by design in the 'mixing' mechanism.  That's the assembly in which cyclic and collective adjustments are consolidated to affect change to the swashplate.


Just a pilot (retired, so I have a LOT of time)...
