Okay, all the parts are on hand.
Let's get started.
facing up. Secure with a washer and #6-32 hex nut. Finger
tighten only, as you will be coming back and adding thread
lock to the nuts later.
Using four #4-40 x 1/2" or #4-40 x
3/8" machine screws, attach the motor
to the motor platforms as shown in
Figure 4. Use four #4-40 lock nuts to
secure. Note that I don't show any #4
washers. If you want, you can add
them to the screws on the underside
of the platform. I have found that the
locknuts work fine without them. Once
complete, set aside.
Using four #6-32 x 2" machine screws and washers,
insert the screws into the holes on the bottom of the
platform shown in Figure 6. Secure with a #6 washer,
1/2" nylon spacer, and hex nut. Finger tighten.
Using four #6-32 x 1" machine
screws and washers, attach the boom
to the platform using the holes shown
in Figure 5. Notice the orientation of
the holes on the top and the bottom
platforms. They must be the same.
Also, the slot in the booms is

Use a 1/8" drill bit and enlarge
the two holes on each of the landing
gear pieces. Next, place the holes in
one set of the landing gear legs, up
against the two front screws
protruding from the bottom of the
platform. Use a screwdriver to twist
the screws until you pull the landing
gear up tight against the lower
platform. The landing gear legs are
slightly splayed; you want the legs
toward the front of the craft when
the base of the legs is up against the
platform. Repeat the process with the
two rear screws and the other set of
legs. This set should be splayed
towards the rear of the craft.
Take the two landing gear braces
and slip them over the exposed screws
as shown in Figure 9. Secure with
four hex nuts. You want to add a drop
of blue or green thread lock to each
of the nuts and tighten with a
wrench. Don't over-tighten or you will
damage the braces.
Add thread lock to each of the
four bottom nuts located at the four
corners of the platform. If you are
using green thread lock, you can add
the drops to the top of the loose nuts
and then tighten. If you are using blue
thread lock, you will need to remove
the nut and add a drop to the tip of
each machine screw. Tighten the nuts
with a wrench. Don't over-tighten
