E-flite RV-9 450 Assembly Manual
12. Check that you have a matching wing panel
and servo. The easiest way is one wing panel
has a “N” number, and the servo cover has the
matching text.
13. Tie the string that exits the wing at the servo
opening around the end of the servo extension.
Use the string to pull the extension through the
wing and through the hole at the center of the
wing as shown.
14. Apply 2–3 drops of thin CA in each of the four
pre-drilled holes to harden the surrounding wood
for the servo cover screws.
15. Secure the servo cover to the wing using four
2mm x 6mm sheet metal screws. Use a #1 Phillips
screwdriver to tighten the screws.
16. Use side cutters to trim the rear leg of a control
horn down to 3/16-inch (5mm).
17. Insert the control horn into the pre-drilled
holes in the bottom of the aileron. Use a felt-
tipped pen to trace the outline of the control horn
onto the aileron.
