Section 15: Installing the Control Linkages
Step 12. If the elevator servo has not been electrically
centered, now is the time to do so. Refer to Section 14, Step 9.
Step 13. The short 6" threaded rod will be attached to the
wooden pushrod next. Thread a clevis on the threaded end of the
wire. In order to determine the length of the rod needed, we
suggest you use masking tape to temporarily attach the rod to
the wooden pushrod.
Step 14. With the elevator clevis attached to the elevator control
horns and the servo arm pushrod temporarily taped to the wood
pushrod, measure the rod end hat will attach to the elevator servo
arm. Use masking tape to hold both elevators in the neutral
position. With the elevators at neutral and the servo arm
electrically centered, position the servo end of the wire over the
2nd hole from the center of the servo arm. Mark the music wire at
the location where the bend will go into the hole in the pushrod.
Step 15. Once you're satisfied with the dimensions of the
elevator servo pushrod wire, remove the wire from the wooden
pushrod and make the L-bend at the location you marked. Trim
off any excess wire. Trial fit the music wire rod to the hole in the
wooden pushrod to make sure it fits flush against the wooden
pushrod. It will be helpful to remove the complete elevator
pushrod assembly for the next step.
Step 16. When you're satisfied with the fit, mix a small amount
of 6-minute epoxy and apply to the hole and area where the rod
will fit. Coat with epoxy, wrap with nylon, and allow to cure
completely.
Step 17. Before attempting to reinstall the completed elevator
pushrod, make sure the epoxy has cured completely.
Step 18. Reinstall the elevator pushrod and clevises and attach
to the elevator control horns and elevator servo arm. Make any
necessary mechanical adjustments so the elevators are at nuetral
when the servo arm is electrically centered. Adjustments can be
made by screwing the clevis in or out, and moving the rod in or
out on the servo arm. We suggest you install 5–7 mm sections
of fuel tubing over each of the clevises to make sure they do not
open accidentally.
Step 19. The rudder pull-pull type of linkage is made up of
music wire (.020), four threaded couplers, two clevis, screws,
and hex nuts. You will make up two sets of linkages.
Step 20. Scrape or clean the ends of each piece of music wire.
Using a soldering iron, silver solder one of the threaded couplers
on one end of each piece of music wire.
Note: It's important to bend over approximately 3/8" of the
music wire onto itself at the ends using some pliers. This
will give a more secure mechanical solder joint as the silver
solder has more to "grab onto" than a straight end.
Step 21. After the solder has cooled, check the security of the
solder joint by pulling on the connection. Attach a clevis on the
threaded coupler and insert the other end through the fuselage.
Attach the clevis to one of the rudder control horns. Do the same
with the other pull-pull linkage. Note that we have removed two
of the servo arms to allow more freedom of movement.
