1. Secure a hub to the shorter end of an L-bracket with two flat-tip screws and nuts positioned as shown in the photo above.


2. Secure the L-bracket to the servo bracket with two flat-tip screws and two nuts positioned as shown in the photo above.


3. Insert a 1/16” hex-head screw through the hole in the servo bracket that is farthest away from the L-bracket and put a washer over the screw.


4. Attach the side of the C-bracket with a single hole onto the screw.


5. Put the cap on the screw and tighten the screw with the 1/16” hex key and crescent wrench as shown in the photo above. Tighten the screw enough to close large gaps between the washer and brackets and to prohibit the C-bracket from wiggling. The joint should pivot easily and freely.


6. Direct the HS-422 servo wires away from the hub and position the servo in the stem joint, as shown in the photo above.


7. Secure the servo to the bracket with two push-rivets at the top of the servo bracket and two at the bottom.


8. While holding the servo as shown in the photo above, gently turn the round servo horn counterclockwise as far as it will go, and position the C-bracket parallel to the servo. Line up the holes in the servo horn with the holes in the C-bracket, slowly turning the servo horn clockwise for precise alignment, if necessary. Secure the C-bracket to the servo horn with two pointed-tip screws.


9. Secure a hub to the center of the C-bracket with two flat-tip screws and two nuts.


10. Hold the HS-422 servo as shown in the photo above. Position the top half of the flower stem above the stem joint. Rotate the top half of the flower stem until the L-bracket with the hub attached to the hexagon is on the left side of the stem joint.


11. Attach the top half of the flower stem to the stem joint’s hub and secure it with a 3/32” hex key and a cap screw from the hub kit.


12. Compare the top half of your flower stem and stem joint to the photo shown above.
