Linkage mount position force and travel
The diagram below illustrates the maximum travel and force available at each linkage
mounting point. As can be seen, the closer you mount the linkage to the shaft, the more force
the servo can deliver. However, this also means the travel of the arm is shorter. Again,
ensure that the servo arm is nowhere near going over-center throughout the entire range of
the control system.
Position A should be used in most RV-4/8 pitch installations. Modify mount position with
caution and take all precautions to ensure that a near over center condition cannot occur.
The autopilot safety shear screw should NEVER be removed or adjusted during this
operation. If the shear screw has broken and needs replacement, there is specific
documentation available for this purpose a
