Main Landing Gear Installation - Model Tech Blue Max Assembly Instructions Manual

Cut away all but one arm from a "4-point" servo horn, then enlarge the hole
that is 5/8" (16mm) out from the centre of the servo horn, using a 5/64" (2mm)
diameter drill bit.
Install the 90º bend in one pushrod wire into the hole that you enlarged in
the servo arm, using one snap-keeper.
The pushrod wire should be orientated on top of the servo arm.
Carefully slide the pushrod wire into the elevator pushrod wire guide tube
(the guide tube on the left side of the fuselage).
Centre the elevator servo, then install the servo horn onto the servo,
making sure that the servo horn is centred and points toward the side of the
fuselage.
Install the servo horn retaining screw to secure the servo horn to the servo.
STEP 3: INSTALLING THE ELEVATOR CONTROL HORN AND CLEVIS
Position and mark the mounting hole locations for the control horn on the
bottom, left side of the elevator. When aligned properly, the centreline of the
control horn should be 3/4" (19mm) out from the fuselage side (measured at
the hinge line) and the clevis attachment holes should be lined up over the
hinge line. The base of the control horn should be angled slightly toward the
fuselage side so that it will line up with the pushrod wire.
Drill 5/64" (2mm) diameter pilot holes through the elevator 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.
The C/A will harden the surrounding wood, making the mounting area
stronger.
Install the control horn and backplate, using two M2 x 20mm machine
screws, then use wire cutters to cut the top of the screws off flush with
the control horn backplate.
Use a couple of pieces of masking tape, taped between the elevator and the
stabiliser, to hold the elevator centred.
With both the elevator servo and the elevator centred, thread one clevis
onto the pushrod wire, then snap the clevis into the third hole out from the
base of the control horn.

STEP 4: HINGING THE RUDDER
Hinge the rudder to the vertical stabiliser, using the same techniques that
you used to hinge the elevator to the horizontal stabiliser. The rudder is hinged
using two hinges. When hinging the rudder, the tips of the rudder should be
even with the tip of the vertical stabiliser and there should not be more than
a 1/32" (1mm) wide hinge gap.
IMPORTANT After allowing the C/A to fully cure, pull on the rudder to check the integrity of the hinges. Apply more C/A to the
hinge(s) if necessary.
Mount the tail wheel bracket to the bottom of the fuselage, using three
pilot holes for the wood screws.
Slide the nylon spacer onto the axle, followed by the tail wheel.
Secure the tail wheel to the axle, using the wheel collar and one M3 x 5mm
machine screw. After tightening the machine screw, make sure that the tail
wheel spins freely.
Push the wheel collar on the tail wheel wire up against the tail wheel mounting
bracket, then install and tighten the remaining M3 x 5mm machine screw into
the wheel collar.
