Step 1: The Center Hub
Remove the center hub plates from the plate bag, along with 8 angled
edge clamp sets, 16 M3x45mm screws, 16 nuts, 32 washers, and the 2
aluminum landing gear connectors with 4 mounting screws
Attach the landing gear connectors to the bottom of the bottom center
plate using the holes shown below.

Position the top plate over the bottom plate to ensure that ALL holes are
aligned. Pay close attention to the hole locations to ensure that the clamp
screw holes match on both plates.
4

12/11/2019 Version 2.2
Starting with the inner clamp positions, push 2 M3x45mm screws with
washer down through the top plate, through the clamp set, through the
bottom plate, through another washer, and secure with lock nuts. Do this
for each of the 8 clamp set holes in the center hub. Until the booms are
installed, the nuts should only be hand tight.
5

12/11/2019 Version 2.2
Use 4 M3x5mm screws, 4 washers, and the 4 15mm (small) aluminum
spacers to install the standoffs in the inner most center holes on the
bottom center hub plate for the power distribution board. Push the
M3x6mm screws with washer, up through the plate, hand tighten the
spacer to the screw, and then tighten again using the 2mm hex driver.
Screw the nylon screws into the top of the standoffs so that you can use
them later to mount the soldered power distribution board.
6

12/11/2019 Version 2.2
Next, use 4 more M3x5mm screws, 4 washers, the 4 rubber vibration
isolators, and the 24mm (medium) aluminum spacers to create the stand-
offs for the flight control mounting plate. Push the M3x5mm screws with
washer, up through the plate, hand tighten the spacer to the screw, and
then tighten again using the 2mm hex driver. Screw the rubber isolators
into the top of the medium standoffs. Screw the nylon nuts down a few
threads of the isolators so that later you can mount the flight control
mounting plate.
7

12/11/2019 Version 2.2
Next, use 8 more M3x6mm screws, 8 washers, and the 30mm (large)
aluminum spacers to create the stand-offs for the battery tray. Using the 4
remaining open holes on the top center plate, push the M3x6mm screws
with washer, up through the plate and hand tighten the spacer to the
screw. Use the 2mm hex tool to come up through the bottom plate to
finish tightening the screw. Repeat for all 4 holes. Screw 4 more M3x6mm
screws with washers a few turns into the spacers. You will need these
later when it’s time to mount the battery tray.

Step 2: Motor Mounting Plates
Remove the motor mounting plates from the plate bag, along with 8 plastic
clamp sets, 16 M3x45mm screws, 16 nuts, and 32 washers.
Push 2 M3x45mm screws with washer, down through the top of each side
of the motor mounting plate, through the clamp set and secure with a nut.
Do not tighten the nuts. Until the booms are installed, the nuts should only
be hand tight. Repeat this for all 4 motor mounts.

Step 3: Mounting The Motors
WARNING: USING THE BLACK CAPHEAD SCREWS PROVIDED IN YOUR MOTOR BOX IS NOT RECOMMENDED. USING
THESE SCREWS CAN RESULT IN DAMAGE TO THE MOTOR AND AIRCRAFT. PLEASE ONLY USE THE PROVIDED BAGGED
M3X6MM SILVER BUTTONHEAD SCREWS + WASHERS WHEN INSTALLING THE MOTORS ON THE QUADZILLA MOTOR
PLATES. IF YOU USE OTHER SCREWS WITH YOUR MOTORS, PLEASE ENSURE THAT YOU HAVE THE PROPER
CLEARANCE INSIDE THE MOTORS (WATCH THE WINDINGS) ONCE THE SCREWS ARE COMPLETELY TIGHTENED.
Using the provided Mid-Atlantic 2212 motors, 16 M3x5mm screws, 16
washers, and Blue/Medium Loctite, use the steps below to mount the
motors to the motor mounts.
Pre-load the washers to the M3x5mm screws. Line up the holes in the
motor mount with the holes in the motor. Load a screw/washer on to the
2mm hex tool and add a small drop of Loctite to the threads of the screw.
Push the screw through the bottom of the motor mount plate, into the motor
and tighten.
Loctite should be allowed 24 hours to set before your first flight.

Remove the 4 boom tubes from their bags. Slip the partially assembled
motor mounting plates on one end of the boom. Tighten the screws
enough that the mounting plate assemblies are semi-tight, but still able to
slide on the tube.
When tightening the mounts to the tube, tighten each side of the clamp
little by little until the mount is snug to the boom tube. This will allow for
the mount to sit flush and the clamps to close properly on the tube.

Proper motor orientation is crucial to your aircraft flying properly. For this
step, you will need to be sure that the correct motor is mounted in the
correct position. Silver cap motors turn counter-clockwise (CCW) and
black cap motors turn clockwise (CW). Since the battery plate will run
front to back on the center hub, we’ll use 2 of the standoffs as a reference
between front and back. Position the center hub so that 2 of the battery
plate standoffs are close to you and the other 2 are away from you and
insert the CCW boom + motor into the clamp sets on the right and the CW
boom + motor into the clamp sets on the left. Semi-tighten the clamps to
hold the boom in place. On the opposite side of the center hub, mount the
other 2 booms, making sure that the similar motors are diagonal from each
other.
When inserting the boom tubes into the clamps of the center hub, ensure
that the ends of the booms are flush with the inner edge of the inside
clamps. Tighten the screws enough that the mounting plate assemblies
are semi-tight, but still able to twist with your hands. It is important to keep
these booms loose so that the motors can be leveled at the end of the
build. Repeat this for all 4 booms.
Keep in mind that the clamps on the entire frame must be tightened evenly so that the
frame plates and motor mounts are as straight as possible. This can be achieved by
tightening each side of each clamp little by little.

Step 4: Landing Gear
Remove one landing gear half from the landing gear bag. The photo
below shows all hardware supplied for the landing gear..
14

12/11/2019 Version 2.2
Load the landing gear down tubes into the the aluminum connector that
you installed to the bottom center plate in the previous steps. Use the
smallest screws in the pre-drilled, threaded holes to secure each landing
gear leg. Leave this screw somewhat loose so that you can move the
landing leg so that the pre-drilled hole will match up with the aluminum “T”
connector to attach the landing skids in the next step.
15

12/11/2019 Version 2.2
Connect one aluminum “T” joint to the bottom of the landing gear down
tube using the longest screw provided in the landing gear kit. As you
tighten the screw, the aluminum piece will tighten agains the landing skid,
preventing it from sliding fore and aft.
Slide the tip pads on to the skids. Repeat for the other landing gear half.
Tighten all screws on the landing gear. This step is now complete.
