Build Instructions
Stick a square of double sided tape to the side of the battery cage that
has the switch. Peel off the other side of the double sided tape and place
the battery cage onto the large Perspex plate,
making sure the switch on
the battery cage goes through the hole in the plate
as shown to the
right.
Take the micro switches and attach them to the
underside of the buggy
using the small M2 nuts and bolts, with the levers sticking out from the
sides of the buggy. Then, using the supplied wire, connect the terminals
on the switches labelled ‘COM’ on the two switches together. Using a
separate piece of wire connect the terminals labelled ‘NO’ together in the
same fashion.
Finally, solder one end of a 10cm length of wire to either of the ‘NO’
terminals and one end of another piece of wire to either of the ‘COM’
terminals. The other ends of these wires will later be connected to the PCB.
Cut two more 10cm lengths of wire and strip and solder one to each
terminal of a motor, as shown in the image to the right. Repeat this for
the other motor.
Take two of the small ‘T’ shaped pieces and push one through the slot in
the bottom of the plate pictured right (the top is the side you put the
battery cage onto). Take the other ‘T’ shaped piece and hook it into the
notch on the side of the chassis. Then push a long 30mm bolt all the way
through from the hole in the ‘T’ piece on the outside of the buggy,
through the hole in the motor (make sure the axel is facing outwards) and
into the hole on the other ‘T’ piece. Once this bolt is all the way through
secure it with a nut.
Repeat this for the second motor on the other side.
