4 Attach bottom motor to arm
Place the assembled bottom motor
against the bottom of the arm with
the short end of the plate facing
towards the end of the arm. Apply
threadlocker to the ends of the two
25 mm bolts (less than one drop
covering four or five threads at the
end of the bolt). Place a 19 mm
hollow spacer between each of the
pairs of holes in the two motor plates.
Place the 25 mm bolts through the
motor plates and spacers, and secure
from below with a metal nut.
