IMPORTANT Remember to apply a couple of drops of thin C/A to the crimp collets.
q Check the tension of the cables. To do this do the following: move the rudder control stick to one side. Let the control stick go and
check to see if the rudder returns to centre. Do this a couple of times in each direction. If the rudder does not return to centre, one or
both cables are too tight. You can adjust the tension of the cables by adjusting the clevises. Ideally, the cables should be as tight as
possible, while still allowing the rudder to return to centre. The cables should not have slack in them, yet they should not be so tight
that the linkage and/or the servo bind.

q Thread one clevis onto two threaded couplers, then attach the clevises
into the holes that are 9mm (3/4") out from the centre of the servo horn.
q Install the servo horn onto the servo, making sure that it's centred.
q Hold the rudder centred, using several pieces of masking tape.
q Attach the cable from the left side of the rudder tiller arm to the threaded
coupler on the left side of the servo arm, then attach the length of cable from
the right side of the rudder tiller arm to the threaded coupler on the right
side of the servo arm, using the same techniques that you used to attach
the two cables to the rudder tiller arm.
IMPORTANT Make sure that both lengths of cable are pulled tight.
There should not be any slack in the cables.
q Install two engine mounting beams onto one nacelle, using four socket-cap
screws and four washers provided. Make sure to space the engine mounting
beams the same width as your engine and notice that the engine mounting
beams are installed angled down.
IMPORTANT The engine mounting beams are adjustable to fit the
width of different sized engines. Make sure when you adjust the width of
the engine mounting beams to fit your engine that you keep the mounting
beams centred on the firewall.
q Install your engine onto the engine mounting beams, using the four
machine screws, four flat washers, four split washers and four hex nuts
provided.
IMPORTANT The front of the your engine's drive washer should be
114mm (4-1/2") in front of the firewall.
q Repeat the previous procedures to install your second engine onto the
other nacelle.
q Working with the right-side nacelle for now, install one throttle servo into
the servo mounting hole in the servo tray.
IMPORTANT The servo output shaft should be toward the back of
the nacelle.
