supplied with the servos. Deploy the servo leads as shown in the illustrations.
49. Use a knife to pierce slots in the left and right fuselage shells (74 and 75) at the marked
points to accept the cabane struts and the undercarriage legs. Open up the slots to the
correct size using the carbon rods.
Take care not to cut the slots longer than the
marked size.
50. Sand the plywood undercarriage doublers (76) to match the curvature of the fuselage,
and glue them in place using UHU-por. The slots in the fuselage and the undercarriage
doublers should line up when viewed directly from above.
51. Glue the front and rear cabane doublers (77, 78) in place using UHU-por.
Keep to the
dimensions stated in the photo.
52. Apply pieces of glass-fibre tape (28) over the doublers to reinforce the joints.
53. Before the next stage you should provisionally fit the fuselage shells over the basic
structure to establish where you have to press the shells into place. Lay the fuselage
structure on the bench, projecting over the edge as shown, and weight it down. Apply
UHU-por to the fuselage structure and the edges of the shell, and allow the adhesive to
air-dry for one or two minutes. Just before fitting the half-shell on the structure, apply
UHU-por to the edges of the side panel and the fuselage former
(wet joint)
. Now fit the
half-shell and press it into place. Repeat the procedure with the second fuselage shell.
Then glue the elevator to the fuselage semi shells.
54. Chamfer the leading edge of the elevators (79) at 45° as shown. Glue the horns (56) in
the slots in the elevators using foam cyano.
55. Attach a threaded coupler and clevis to one end of each of the elevator pushrods (1).
Connect the prepared pushrods to the elevator horns, and apply the glass fibre tape
(28) as shown.
56. Slip the elevator pushrods into the fuselage through the outer sleeves and into the vacant
holes in the Duo pushrod connector. Offer up the elevators to the tailplane, and set
them to neutral (centre). Tighten the grubscrews in the Duo pushrod connector to clamp
the pushrods.
57. Sand the whole surface of the carbon undercarriage reinforcements (6), and lightly sand
the carbon undercarriage legs (5) over the length of the joint area with the
undercarriage reinforcements (6). Glue the two pairs of parts together using thick cyano,
taking care to keep the edges flush.
58. Drill a central 4 mm Ø hole at the end of each undercarriage leg at a point 15 mm from
the bottom edge. Pull the drill downward as shown, so as to obtain an angled hole; the
angle should be about 60°.
59. Insert the undercarriage legs in the fuselage
(do not glue them)
, and fit the wheel axles
(9) in the angled holes. Lay a steel ruler between the right and left undercarriage legs,
and position the wheel axles parallel to the building board and with slight toe-in; tack the
axles to the legs with a little thin cyano. You can check that the angle is correct by
placing the undercarriage legs side by side as shown; the wheel axles should then be
about 2 mm apart at the top. When you are satisfied, apply 5-minute epoxy round the
axle joints to reinforce them.
