3. Use the servo lead strings that you used previously for the
aileron installation to help you route your elevator servo leads.
Tie a spare nut or a servo wheel to the end of the string.
❏
4. Route the string into the fuselage through each elevator
servo bay and route it up and over the two formers in the fuselage.
This will prevent your elevator servo leads from rubbing on or
becoming tangled with the rudder pull-pull system.
❏
5. Install the elevator servos with the output shafts facing
forward. Use the screws that came with your servos.
❏
6. Center your servos and install a long servo arm onto
each elevator servo. Choose the arm that points up and is 90
degrees to the servo case. Cut off the unused arms.
❏
7. Using a straightedge, project a line from the servo arm
to the elevator. Make a mark on the elevator for the control
horn. Do this for both elevators.
❏
8. Install the elevator control horns using six (6) 2-56 x 1"
[25mm] machine screws. Use a 5/64" [2mm] drill bit to drill
the holes.
❏
9. Locate two (2) 6" [152mm] pushrods and two (2) plastic
clevises. Thread the clevises onto the pushrods so that 1/16"
[1.6mm] of thread is exposed on the inside of the threaded barrel
of the clevis. Slide a silicone clevis retainer onto the pushrods.
