The RV-10 pitch mounting kit includes a mounting bracket for use with the linear actuator and most
of the required fasteners to mount the servo and properly link it to the aircraft control system. Refer
to the drawings to locate the servo mounting bracket in the aircraft.
Fasteners along the mounting plate surface must be removed and can be re-used to secure the
bracket in place. The Dynon mounting bracket must be drilled to match the existing hole pattern of
the aircraft plate. Once the bracket has been drilled, fasten it to the aircraft. It is up to the installer to
verify the hardware used is tightened back to aircraft specification. With the bracket installed in the
aircraft, the bell crank must be drilled with a #12 drill bit for a .189 inch hole diameter. Refer to Fig
4 for hole placement. Install the 4 AN3H-3A bolts and MS35333-39 star washers to secure the servo
to the bracket per the drawing. All AN bolts supplied by Dynon have drilled heads for use with
safety wire. With the servo and bell crank additions in place, torque all fasteners back to original
installation specifications and add safety wire where needed.
Thread the rod end with jam nut into the end of the linear actuator closest to the bell crank. Refer to
the illustration and follow proper rod end installation techniques. Connecting the linear actuator to
the elevator bell crank will require the AN3H-14A bolt, AN970-3 large diameter flat washer (for
capturing the rod end bearing), 3 AN960-10 flat washers, the 0.485” aluminum spacer, and the
AN365-1032A lock nut. Verify the control stick is set to neutral and the linear actuator travel is
approximately centered, adjusting the rod end as needed to achieve this. Once the linkage is
tightened, move the stick to full pitch up and down and verify the linear actuator is not restricting
further movement.
Your servo(s) and AP74/76 (if ordered) came with a CD containing the latest documentation for all
Dynon products (also available at dynonavionics.com). Please read through that documentation to
understand the wiring and configuration process for your Autopilot system. We also maintain a
collaborative set of this documentation, which is often updated with new information by both
Dynon and fellow builders. Visit wiki.dynonavionics.com to view and contribute to the latest
version of these documents. Also visit forum.dynonavionics.com to discuss and share installation
notes, pictures, and suggestions with other builders.
