Attach Elevons to Servos
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.)
(See Figure 19)
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 movement of the elevons. Mark the position of the
control horns. Drill two holes with 3/32” drill for each control horn. 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 threaded control rods.
(See Figure 18)

Make a Z-bend by making two 90 degree
bends in the control rod. Push the rod
through the servo output arm.

Make a 10 degree bend in the control rods 1 inch behind the servo to prevent binding.
Beginning flyers put the clevis in the 1st or 2nd hole from the top for less response. Ex-
perienced flyers put the clevis in the 3rd or 4th hole from the top for more response.
