q Repeat the previous procedures to installed the second threaded axle and main gear wheel.

q Plug one 600mm (24") servo extension onto each elevator servo lead.
q To prevent the plugs from pulling apart during assembly, or worse, during flight, secure each of the plugs together, using a short piece
of 10mm (3/8") diameter heat-shrink tubing (not included). Use a heat gun to shrink the tubing.
IMPORTANT When you run the elevator servo extension leads up to the radio compartment, make sure that the extension leads
won't interfere with the rudder pull-pull cables when they're installed later. Tape them securely to the fuselage to keep them out of the way.

q Install the control horn and backplate, using two M2 x 25mm machine screws. Use wire cutters to cut the screws off flush with the
control horn backplate.
q Slide one main gear wheel onto the axle, then secure the wheel into place,
using one wheel collar and one grub screw.
+
Tighten the grub screw firmly, then double-check that the wheel spins
freely.

q Install one elevator servo into the servo tray in each side of the fuselage.
There are predrilled pilot holes for the servo mounting screws, although you
may need to drill new pilot holes if the predrilled holes don't line up with your
particular servos.
IMPORTANT Both servo output shafts should be toward the front of the
fuselage.
q Position and mark the mounting hole locations for one control horn on
the bottom of the right elevator half. When aligned properly, the centreline of
the control horn should be 16mm (5/8") out from the end of the elevator half
(measured at the hinge line) and the clevis attachment holes should be lined
up over the hinge line.
q Drill 2mm (5/64") diameter pilot holes through the elevator half for the control
horn mounting screws, then apply a couple of drops of thin C/A into the pilot
holes and allow the C/A to fully cure.
IMPORTANT The C/A will harden the surrounding wood, making the
mounting area stronger.
