Install The Elevator And Rudder Servo - GREAT PLANES SR22 Turbo Instruction Manual

❏
8. Gather together a couple of sheets of paper towel,
denatured alcohol, mixing cup, mixing stick, epoxy brush, 8"
[203mm] or longer wire (not included) and 30-minute epoxy.
❏
9. Mix together 1/2 oz. [15cc] of 30-minute epoxy. Apply
epoxy between the lines on the aluminum tube. Center the
tube. Use a paper towel dampened with denatured alcohol to
wipe away any epoxy before it runs down the fuselage. Apply
epoxy to the rest of the aluminum tube. Using the long wire
apply epoxy inside the tube in both stabilizer halves and to
the root of both stabilizer halves. Slide the stabilizer halves
onto the aluminum tubes so that they are tight against the
fuselage. Use masking tape to hold the stabilizer halves in
position. Wipe off any excess epoxy.
❏
10. After the epoxy has cured, insert the elevator joiner
wire, making sure that the marked left side of the wire is on
the left side of the fuselage.
❏
11. Remove the six pivot point hinges. Apply a small drop
of oil to the pivot point on the hinges. This will prevent the
epoxy from adhering to the pivot point. Make sure oil does
not get on the gluing surface of the hinge. If it does, clean the
oil off with a paper towel dampened with denatured alcohol.
❏
12. Mix approximately 1/4 oz. [7.4cc] of 30-minute epoxy.
Use a toothpick to thoroughly apply the epoxy in the holes
for the hinges in the stabilizer and elevator halves. Also apply
epoxy in the holes for the elevator joiner wire in the elevator
halves. Wipe off any excess epoxy around the outside of the
holes with a paper towel dampened with denatured alcohol.
Use the toothpick to apply epoxy to the ends of the hinges that
go into the stabilizer. Insert the hinges into the stabilizer and
wipe away any excess epoxy that squeezes out of the hole.
Apply epoxy to the other end of the hinges. Join the elevator
halves to the stabilizer, pushing the hinges only about 3/4 of
the way into the elevator halves. Use a toothpick to remove
any excess epoxy the squeezes out. Then, fi t the elevator
halves the rest of the way on.
Move the elevator up and down a few times to help align
the hinges and make certain that the elevator halves defl ect
up and down enough. Allow the epoxy to cure, checking it a
couple of times while it cures.

1. Insert a 2-56 x 36" [914mm] metal pushrod in the
hole on the aft left side of the fuselage.
❏
2. Mount the elevator servo in the radio tray. Remember
to harden the screw holes with thin CA.
❏
3. Thread a nylon clevis 20 turns onto the end of the elevator
pushrod. Slide a silicone clevis retainer over the clevis. Install
the clevis in the outer most hole of a nylon control horn.
