The control rods may not fit in the servo control arm. The end of the
control rod can be filed to fit in the servo control arm or the top hole in the servo control
arms can be reamed by spinning an X-acto #11 blade in the hole or drilling with a #48 drill
(.076”). Attach control rods to the servo control arms with a Z-bend. (NOTE: Z-bend
pliers may be purchased from your local hobby store to make this operation easier).
Position the control horns on the elevon directly behind the servo control arm close to the
hinged edge but be sure the control horn and screw plate do not interfere with the move-
ment of the elevon. Mark the position of the control horns. Drill two holes. Install the
control horns on the elevons. Note that the two screws will self thread into the plastic
screw plate. Attach the control rods to the top hole of the servo control arms. Attach the
clevises to the control horns. It may be necessary to put a slight bend in the control rod
about 1 inch from the servo to prevent hitting the wing. Beginning flyers put the clevis on
the 1st or 2nd hole from the top of the control horn for less response. Experienced flyers
put the clevis in the 3rd or 4th hole from the top for more response.
