Trio Avionics Wing Servo Mount Installation for RV-4 and RV-6 - Manual (Page 9)

WARNING
Verify bellcrank freely rotates throughout its entire range*. Ensure all hardware has
sufficient clearance from bellcrank mounting struts and all other wing structure as shown
in image below. Verify that no “over center” conditions are possible. Confirm the servo
push/pull tube doesn’t bind as the controls are moved throughout their entire range.
Check all clearances
* Aileron control travel limits are defined by Van’s. Limits are set by mechanical stops that
are attached to the airframe. Following installation, verify aileron travel is limited by the
mechanical stops on the airframe, NOT BY THE ROTATIONAL LIMITS OF THE SERVO.
If you do not have experience working with aircraft control rigging, please seek the advice
of an EAA Technical Counselor or someone else with appropriate skills and experience.
