Hello,

I do fly an homebluild Lancair 320 and have installed about 5 years ago a
S-TEC 50 autopilot P/N 0131-10-1  S/N2737C.
The servo actuator for the elevator is directly coupled to the elevator push
rod via excenter disk and a small rod.
From the beginning on I do have some problems with slight oscillation in
this axis.
Could you give me some information and/or practical results from other
aircraft owern of this typ:
- what is best location of the elevator servo actuator
- what method is best to couple in:  excenter disk or cable type
- neccecary modifications to thy system 50 computer
- contact / experience / suggestiones of other builders

thank you very much for your help!
