The RV-6/7/9 fuselage pitch servo mounting kit includes a mounting bracket, pushrod linkage, and
most of the required fasteners to mount the servo and properly link it to the aircraft control system.
All Dynon-supplied parts are illustrated in dark grey to distinguish them from existing aircraft
hardware. Refer to the drawing to locate the servo mounting bracket, and remove existing fasteners
as needed from that location to allow clearance for the bracket to sit flush against the spar. The
flange at the bottom of the bracket can be used to rivet through the fuselage floor, or this flange can
be trimmed off. It is up to the installer to fasten the bracket using appropriate hardware, whether
that be match drilling the holes along the spar and installing rivets or using AN bolts and nuts to
secure the bracket in place (these fasteners are not available from Dynon).
With the bracket installed in the aircraft, the bell crank must be drilled. Refer to the drawing for
dimensions, and use a supplied AN960-10 washer as a support between the two halves of the bell
crank to avoid crushing when the linkage is fastened.
Install the 3 AN3H-3A bolts, MS35333-39 star washers, and AN960-10 flat washers to secure the
servo to the bracket per the drawing, noting the orientation of the servo output arm. 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.
With the servo installed, the linkage needs to be assembled. Refer to the illustration and follow
proper rod end installation techniques. Screw at least half of the threads on each rod end into the
push rod. To prevent the possibility of the servo arm going over-center, the servo arm
must not travel more than a total of +/-60º from neutral throughout the control system's range of
travel. The linkage should be installed as close to the Dynon recommendation as
possible, as
