23. Once the elevons are hinged you can cut out access holes for the servo control
arms; plug in the servos; and allow the arms to center.
24. The control rods should run perpendicular to the hinge line. Use a fine tip marker to
mark the holes for the horns and a small drill bit to make the holes for the screws. Once
the holes are marked and drilled you can install the horns.
25. With the wing flat in the top beds and the bottom of the wing facing up you can use
a straight edge to ensure the bottom of the wing airfoil towards the trailing edge and
the bottom of the elevon are flush. This should help set proper reflex for your maiden
flight. You can now measure and bend the 2-56 control rods for the elevons.
26. There are EZ Links in the small parts bag that will allow you to bend a 90 degree
angle in the control rod and attach to the servo control horn.
Fuselage Prep
27. Now that the wing is complete you can tape the fuselage halves together with the
rudder in place to prepare for test fit of components and CG testing.
NOTE: We recommend using regular masking tape for the following steps as blue or
“painters” masking tape does not stick well to EPP.
28. Once the fuselage is taped together you can mark the CG range on both sides of the
fuselage.
The recommended CG range is from the leading edge of the wing saddle to
3/8” behind the leading edge.
Use a straight edge and a fine tip marker to mark this
range on the bottom edge of the fuselage on both sides.
29. Place the wing in the saddle and then tape your motor, ESC and any other gear you
plan to fly onboard in their approximate locations.
30. Using the tail pin as a balance bar, position the fuselage so that your forward CG
marks are centered over the pin.
