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.

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.

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.

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.

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.

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.
