Finished view of the Twin Brushless motor kit installed in the Walkera 53Q/53QD.

Now, its time to install the brushless kit. Carefully unwrap and take
out the brushless motor kit with nylon tie wraps.

Motor "A". It is the motor that is next to the Rx. Then install
brushless Motor "B". It is the motor that is next to the tail section.

Make sure that the gears are meshing well by spinning the rotors.
Adjust the motor mounting screws accordingly. You should be able
to freely spin the rotors. With your hand spin the top rotor and low
rotor. They should be able to spin at least one rototion when you
give each rotor a spin with your hand. If they do not, then you need
to loosen the motor mount screws so that the pinion meshes easier
against the main gear. Repeat the above procedure with the lower
rotor.

(NOTE: TOO TIGHT MOTOR MESHING WILL CAUSE THE ESC TO HEAT
UP OR BURN OUT THE ESC MAKING THE BRUSHLESS MOTOR
UNABLE TO WORK PROPERLY. TOO LOOSE WILL STRIP THE MAIN
GEAR.)

Screw back on the four corner screws that connect the airframe to
the battery tray holder.

Now, let's connect the electronics. Bascially, you need to connect
the TWO SIGNAL WIRES (BLACK/RED JST MALE connctors to the Rx.)

Once connected, you should tie down the wires, ESC's, and Dual
Brushless Signal converter with the included nylon tie wraps. The
Dual brushless signal converter is very FRAGILE. Do not SQUEEZE
the chip in the center. Hold the dual signal converter at the edges.
Squeezing the chip will damage the clock chip.

After tying down everything, it should look like this.

Put on the flybar rod and the blades. You will want to test
everything before putting on the fuselage. Make sure all off the
wires are not touching any of the main gears. Start up the
helicopter by binding it to the TX. You will hear some short beeps
from the brushless motors. Once the beeping stops and the RX
stops blinking, check your servos by moving them left, right,
forward and backwards. Make sure they have been properly
RE-Connected. Make sure the swashplate is level with the ground.

Okay, you should now be able to throttle up the helicopter. One
rotor will always spin first before the other. If the helicopter is
tending to spin left more or right more, compensate by adding more
TRIM the opposite way until most of the spinning is nominal. Use
the lower TRIM Tab on the Throttle stick.

Once everything is working properly, you can put the fuselage back
on by doing the opposite procedure from the beginning
instructions.

First we need to remove the two 370 carbon brushed stock motors.
Remove all four blades and the rotor flybar rod. You will need a
small phillips screwdriver, small pliers, and 1.5mm hex driver.

The Main rotor shaft should look like this after removing above
items.

After removing the above items we now need to remove the
fuselage. Using a small phillips screwdriver remove the fuselage.
There are four small screws located at the middle of the fuselage.
Two on top and two on the bottom. There are also two small screws
near the front of the canopy. Remove the screws. The fuselage has
two small plastic holders the connect the canopy to the airframe
Carefully pull out gently the plastic fuselage holder. Repeat on the
other side. Slide out canopy HALFWAY.

Gently pull out the fuselage half way. Then carefully disconnect the
L.E.D. Power Plug that connects to the RX. It is very small, so be
careful when tugging gently out.

You should now be able to remove the entire fuselage.

Disconnect the two carbon stock motors. First remove the
connection from the RX to the two motors. Then remove the four
screws underneath the battery holder to remove the landing gear
and battery holder.

Unscrew the two stock carbon brushed motors and place in a safe
place as you will not be using these motors anymore.
