Slide the 1680 ball bearing over the main shaft. It doesn’t matter
which way the ball bearing goes.
Push the bearing down the shaft so that it rests at the bottom
(see dotted red line).
3
4
Once the bearing is sitting flush to the bottom of the shaft, fit
the E7 E-ring on top of it (see dotted red line).
Make sure that the E-ring is positioned so that the rounded
surface is facing upward.
5
6
Clip the E-ring into place with needle-nose pliers.
Prepare the 46T gear you built in Stage 1, and check that the
three screws are fully tightened. If any are loose, simply tighten
them with a screwdriver.
170
7
Place the 2.5 × 16mm pin into the hole in
the middle of the main shaft (circled).
™
8
9
Adjust the pin so that equal lengths are
protruding from each side of the shaft.
10
Push the gear down so that the ends of the pin sit inside
the grooves in the back of the gear (marked with the
dotted red lines).
Making sure the pin doesn’t fall out,
slide the 46T gear over the main shaft,
back side first.
11

Thread-locking agent (or rubber-based
adhesive)
172
Main shaft assembly (Stage 36)
Sealable plastic bag
Marker pen
Place the set screw onto
the tip of the Allen key.
7
Apply a little threadlocking adhesive to the
set screw (rubber-based
adhesive can also be
used).
1
Place the set screw into
the threaded hole in the
side of the main shaft
cup joint (circled). Do this
immediately, before the
thread-locking agent or
adhesive dries.
3
Look into the main hole
of the cup joint, and keep
turning the set screw until
the end of the screw is
visible, as shown.
™
Push the 1680 bearing
onto the tip so that it sits
flush with the body of the
cup joint.

6
Remove the tape from
the tip of the main shaft
assembly built in Stage 36.
9
™
10
Place the cup joint and bearing assembly onto the tip of the main
shaft, as shown. Make sure that the flat portion of the shaft's tip
fits into the corresponding flattened section of the inside of the
joint (see arrow).
11
Push the cup joint down so that it rests against the gear. If it is
difficult to push it, loosen the set screw a little.
12
Applying pressure with your hands to keep the parts tight to
each other, tighten the set screw firmly with the Allen key.
Holding the Allen key so that its shorter arm is in the screw and
its longer arm is in your hand will make it easier to tighten, as you
are given greater leverage.
Assembled parts
As you have done in earlier stages, keep any unused parts in a
plastic bag, and mark the stage number for ease of reference.
174
™
Stage 38
Assembling the main gear
Your parts
Center gear (20T)
Main gear (46T)
Tools and
materials
1480 ball bearings × 2

175
Fit the 20T center gear
into the center of the 46T
main gear.
7
Adjust the center gear so
that the circled holes line
up with those on the 46T
gear, and that it is fitting
snugly into place.
1
From the back, insert the
first 3 × 8mm countersunk
screw into one of the
holes (see arrow).
3
Insert the next two 3 ×
8mm countersunk screws.
Again, tighten lightly at
first: when all three are in
lightly, tighten each fully.
™
Tighten with a
screwdriver, but not too
firmly at this stage.
4
Place the first 1480 ball
bearing into the space
in the center gear, as
arrowed. It does not
matter which way the
bearing goes.

Hold the first bearing in
place from the back, then
place the other bearing
into the corresponding
space at the front of the
center gear.
Press the bearing into
place, making sure it is
sitting straight.
™
9
10
Inspect the main gear shaft supplied with Stage 37.
You will see it has a ‘collar’ near the center of the
shaft, and that this divides the shaft into a longer
and shorter end.
Place the longer end of
the main gear shaft into
the front of the center and
main gear assembly, as
shown by the arrow.
11
Pull through from the
back so that the parts are
flush with each other, then
use masking tape to hold
the shaft in place.
13
Slide the shaft into the
gear so that the collar
rests against the 1480 ball
bearing.
12
Check that your assembly
matches the one in the
photo, and that the tape is
holding the parts in place
securely.
14
Assembled parts
177
Store your assembly in a sealable plastic bag.
This is especially important for the parts that
make up the gears, as any dust that gets into
these parts may cause difficulties at a later
stage.

1
Place the center gear
mount front flat on your
work surface, as shown. The
center gear mount front and
back parts look very similar,
so make absolutely sure
you select the front part.
Place one of the 3 × 12mm
binding-head screws into
the first hole, as shown.
2
Turn the screw with a
screwdriver, making sure the
screw enters the gear mount
perfectly straight. When you
feel the screw reach the far
side of the mount, carefully
remove the screw, again
making sure to keep the
screw straight.
3
Repeat Steps 1 and 2 for
the other hole, so that both
holes are left with the screw's
indentations, forming the
'tapped' inside (see circles).
4
Remove the masking tape
from the main gear assembly
built in Stage 38.
5
Insert the tip of the main
gear shaft into the hole
in the underside of the
center gear mount back,
following the arrow.
6
Next, re-familiarize yourself
with the proportions of the
center gear assembly built in
Stage 37. The left side is thicker
and the right side is thinner.
7
Making sure not to dislodge
the main gear, place the
center gear assembly into
the second hole on the
underside of the gear mount,
as shown.
8
Adjust until the teeth of the
center gear engage fully
with those of the main gear
(circled). Make sure not to
force the parts, as this may
damage the teeth. Once
engaged, ensure the center
gear is sitting straight.
179
Press the parts firmly
together.
9
Press the parts firmly
together, making sure
that the ball bearing on
the center gear shaft sits
inside the hole of the gear
mount front, as shown.
Place the center gear
mount front part over the
tips of each gear assembly
and press together,
following the arrows.
Check against the photo
that you have the parts
aligned correctly.
10
11
12
It is very important that
the parts fit together
snugly, so check closely
against the photo to
make sure that your
assembly looks exactly
like this.
Place the 3 × 3mm set
screw onto the tip of the
Allen key, and apply a little
thread-locking agent (or
rubber-based adhesive).
13
Inspect the cam section of
the brake cam (pictured) –
there is one short side and
one long side.
™
15
Hold the brake cam level,
as shown, and carefully
insert the set screw. Make
sure that the set screw is
in perfectly straight, then
tighten by two rotations.
14
Position the gear mount
assembly on your work
surface, as shown, then
carefully place the brake
cam into the arrowed slot,
with the short side of the
cam facing you.
180
16
Press the brake cam
into place.
17
Place the brake collar
onto the tip of the brake
cam, with the flange
side facing down.
™
Press the brake collar
down so that it rests on
the upper edge of the
gear mount.
19
Hold the assembly level,
then lower the center gear
cover onto it, so that the
arrowed holes line up.
21
The short side of the cam
should be visible in the
rectangular hole from the
outside of the gear mount.
18
20
22
From above, check that
the circled screw holes
are correctly aligned.
Holding the parts
together, insert the first
3 × 18mm self-tapping
screw into the circled hole
and tighten lightly.
23
Next, repeat for the next
three circled holes. Do not
fully tighten the screws at
this stage.
181
24
™
Holding the assembly in
your hand, as shown in
the photo, insert two 3 ×
12mm self-tapping screws
into the holes at the top
corners. Again, do not
fully tighten yet.
25
Once the two 3 × 12mm
screws, and the four 3
× 18mm screws are in,
tighten each fully with a
screwdriver.
26
27
28
29
Push the brake cam rod through the hole in
the shaft of the brake cam protruding from
the gear cover.
Adjust the rod so that the straight end
sits 1mm away from the side of the raised
section of the gear case, and the looped end
is facing upward, as shown.
Use the 1.5mm Allen key to tighten the set
screw fitted in Step 14 until it presses down
on the rod, stopping it from moving.
Check that the brake cam
is able to rotate by turning
the brake cam rod from
side to side.
30
Check that the gears are
able to rotate freely inside
the mount casing by
turning the center gear's
cup joint. It does not
matter if the parts catch a
little bit at this stage.
Assembled parts
31
Store unused parts safely in a sealable plastic bag, and mark the
stage number on it for ease of reference.

3
Next, place the
corresponding brake pad
over the caliper, making sure
the holes line up.
4
Fit the brake disc over the
protruding cup joint.
5
Place the second brake pad
over the brake disc, so that
its holes line up with those
of the first.
6
Add the second brake
caliper.
7
Place the first 3 × 12mm
binding-head screw
provided in Stage 39 through
the holes on the right of
the brake pads and calipers,
and into the hole in the gear
mount beneath.
8
Holding the parts in place,
gently tighten the screw, but
stop before the head touches
the outermost caliper.
185
Holding the center gear
mount as shown, place the
first brake caliper so that
its two holes line up with
those on the casing of the
mount (arrows). Make sure
you have the orientation
of the caliper positioned
correctly, as shown in the
photo.
™
Tighten the second 3
× 12mm binding-head
screw (Stage 39) into the
wider hole on the left side
of the pads and calipers,
and tighten lightly.
9
11
From the side, your brake
pads and calipers should
look like this. Turn the
screws until there is a gap
of about 1mm between
the outermost caliper and
the screw head.
10
12
The disc brake is
complete, and should
look like this.
Prepare the steering plate and servo saver assembly built in Stage
26. The steering plate is in the middle, with the two servo savers
to the left and right.
Place one of the steering
posts into the hole in the
center of the right servo
saver, from the side that
houses the spring.
13
Insert the other
steering post into the
hole in the left servo
saver from the same
side as you did the first.
15
Push the steering post
through to the back of the
servo saver.
14
Pull the servo savers apart
gently and place the
assembly directly behind
the front bulkhead from
the rear.
186
16
Turn the servo savers until
they line up directly with
the circled holes on the
front upper plate.
17
Tighten the screw,
but not entirely at this
stage, as the lower part
of the steering post is
not fixed yet.
Position the front torque
rod beneath the center of
the front upper plate, as
shown by the arrow.
23
Place the first 4 × 10mm
binding-head screw into
the right hole in the front
upper plate and through
to the hole in the right
servo saver.
18
Repeat Steps 18 and 19
for the left servo saver
and the second 4 × 10mm
binding-head screw.
19
21
Set a 3 × 10mm bindinghead screw into the hole,
as shown.
™
20
Fit the front torque
rod to the upper plate,
so that the contours
of each are flush with
one another.
22
Tighten the screw securely
with a screwdriver.
187
24
25
™
Next, carefully turn
the main chassis over,
and place a 4 × 10mm
countersunk screw into the
hole leading to the bottom
of the right servo saver.
Tighten with a screwdriver.
26
27
28

Back
Front
Front driveshaft
(Shorter)
Lay the main chassis assembly (Stage 40)
on your work surface facing to the left.
Place the center gear mount (also Stage 40)
in the center, as shown here. Next, lay out
both driveshafts – the longer of the two is
the rear driveshaft, and the shorter is the
front driveshaft. The difference in length
is not large, so make sure not to get these
confused.
Rear driveshaft
(Longer)
2
Place one end of the
front driveshaft into the
differential cup joint facing
out of the front bulkhead
(circled).
3
Make sure the metal pin set
into the end of the driveshaft
fits into the two slots in the
cup joint.
4
Holding the driveshaft
carefully so that the end
fitted in Step 2 doesn't fall
out of the cup joint, angle
the center gear mount so
that its protruding cup joint
accommodates the other
end of the driveshaft.
5
Again, make sure the tip
of the driveshaft is fully
inserted into the cup joint.
6
Making sure neither end
of the front driveshaft is
dislodged, fit the tip of the
rear driveshaft into the
second cup joint.
7
Holding the parts together
carefully, fit the other end of
the rear driveshaft into the
differential cup joint beneath
the rear bulkhead.
190
Make sure the metal pin is
fitted into the slots in the
cup joint.
8
Holding the center gear
mount and driveshafts
in place, turn the chassis
assembly around so the
bottom is facing upward,
then place the first 4
× 16mm self-tapping
countersunk screw into
one of the circled holes.
Screw the remaining 4
× 16mm self-tapping
countersunk screws into
the remaining three holes.
When all are in, tighten
each fully.
14
With both driveshafts in
place, lower the center
gear mount down onto
the surface of the main
chassis, so that the four
holes line up with those
on the chassis.
9
Still holding the center
gear mount carefully in
place, tighten the screw
with a Phillips screwdriver.
Do not tighten fully at this
stage.
10
12
Place a 3 × 10mm bindinghead screw into the first
of the holes on the shorter
arm of the roll bar.
™
11
Turn the chassis
assembly around, then
place the roll bar over
the center gear mount,
as shown. The shorter
arm will sit on the
center gear mount itself,
and the longer on the
surface of the chassis
(see arrows).
13
Tighten with a screwdriver,
but do not use too much
force at this stage – the
roll bar should not be
rotated by the turning.
191
15
™
Place the second 3 ×
10mm binding-head screw
into the adjacent hole,
then tighten both fully.
16
Next, inspect the longer
arm of the roll bar – it does
not matter if it has come
away from the chassis
surface a little. Place a
3mm nut into the groove
in the tip of the arm, as
shown by the arrow.
17
18
19
20
Holding the nut in place with your finger,
turn the chassis around and place a 3
× 12mm countersunk screw into the
corresponding hole on the underside of the
roll bar.
Tighten the screw into the nut with a
screwdriver. Be careful not to overscrew, as
this can damage the inside of the nut.
Turn the chassis around and place the
second 3mm nut into the next groove in the
roll bar.
As you did with the
first screw, turn around
and place the screw
into the second hole.
21
Tighten both screws
fully.
