Use the previous sub-assembly
“C” to combine the 2 “B” assemblies
into a lower frame for the car.
Since the wheel arches contain
45 degree geometry, we use
adjustable angled L-brackets to  t
them.

assemblies.
Here we show how
many equal parts to
make of this sub-

It’s time to  x the servo motor to
the car’s frame. It’s enough to use 2
bolts in a diagonal to  x the servo.
Start with putting the rectangular
nuts into the beam, and then
screw the 8mm standoff to the
beams as shown. Then position the
servo (some tweaking needed) and
 x it.

lock nuts should in this step only
be entered with a few turns. This
makes step 18 easier later. They will
be tightened more in step 18.

This step is to make the case
that houses and  xes the steering
mechanism. First you make 4
“legs”, then connect them with
9cm beams into 2 halves. Then
combine the 2 halves with a 4cm
beam. Then attach 2pcs 2-hole 90
brackets as shown in the drawing.

In this step you will build the
wheel barrels. You start by putting
the 2 bearings onto the bearing
axle part (green in picture). The
wheel hex  x (blue in picture) with
M4 lock-nut inserted, is put into
one barrel half. Then clamping the
2 barrel halves over the bearings
and wheel hex  x.

In following steps, these parts
will be used to  x the steering

Sub-assemblies: 2x F , 4x G
In this step you will combine the
2 “F” Sub-assemblies with the “G1
and G2”. Note that we make two
mirrored sub-assemblies, “H1” and
“H2”. One is for right side of car, the
other is for the left. Use lock nuts
M3 and tighten them just enough
to get a smooth rotation “hinge”
movement.

Find your previously assembled
“E” Sub-assemblies, and use lock
nut M3 to attach them to the
previous steps “H1” and “H2” parts.
Tighten the M3 nuts enough so
parts are not loose.

Beams 2x 2cm
The part “J1 and “J2” functions as
the arms to the steering column.
The 2 angled brackets is  xed in a
special way to the beams. They are
put in contact with the 6x10mm
nut and screwed to it. The reason is
to get steering geometry distances
correct.
