"...........Same rotor control box, same cable to the milspec connectors on the rotors.
They both indicate the same.
It's just the Tailtwister that has started weakening..

Any suggestions before I open it up?

I've done normal cleanup and bearing lube before."

Bill.  Normal cleanup and bearing lube of what??? Tower bearing?? or Tailtwister??
Sounds like binding inside the rotor; OR the ball bearings and races need cleaning and re-greasing in the rotor.  They tend to get gummed up after time. Years ago I got some LOW temp grease from Hy-Gain, looks almost like petrolum jelly, yellow in color.  Don't know if you can still get it.

While you've got it apart, may as well check/replace the directional pot.

Just my $.02 worth (experience)

Good luck
