WIND POWERED
RACER
A. SAFETY MESSAGES
1) This kit is intended for children aged 10 and over. All project-related assembly and operations should be done under adult
supervision. 2) The propeller spins at high speed when the motor is turned on. To prevent potential injuries, do not touch it with your
fingers or any objects. Adult supervision is required all the times. 3) Verify that the switch is turned off when inserting/replacing the
batteries. Otherwise the propeller will spin immediately once all batteries are installed. Adult supervision is required. 4) To prevent
potential short-circuits, never touch the contacts inside the battery compartment with any metal object. 5) Carefully examine the plastic
propeller before you put it on the motor's axle. If you see any defects in the blades or on the outer rim, do not run the motor. Refer to the
Questions and Comments section on this sheet and contact our customer service team for a replacement. 6) This kit and the finished
product contain small parts which may constitute a choking hazard if used inappropriately. Keep away from children under 3 years of
age.
B. USE OF BATTERIES
1) Requires four 1.5 V AAA batteries (not included). 2) For best results, always use fresh batteries. 3) Make sure you insert the batteries
with the correct polarity. 4) Remove the batteries from the kit when not in use. 5) Replace exhausted batteries straight away to avoid
possible damage to the kit. 6) Rechargeable batteries must be removed from the kit before recharging. 7) Rechargeable batteries must
be recharged under adult supervision. 8) Make sure the supply terminals in the battery case are not short circuited. 9) Do not attempt to
recharge non-rechargeable batteries. 10) Do not mix old and new batteries. 11) Do not mix alkaline, standard (carbon-zinc), or
rechargeable batteries.

13. Attach the battery case cover (G) to the battery case with 2 small screws.
14. Find a long smooth road, flip the switch to the "ON" position, and watch the Wind Racer speed away! The propeller spins at high
speed when the motor is turned on. To prevent potential injuries, do not touch it with your fingers or any objects. Adult supervision is
required all the times.
E. TROUBLESHOOTING
If the Wind Racer does not run
smoothly:•
Add cooking oil or lubricant
to
the long axle and the front wheel's axle.If the motor does not
run or is running
slowly:•
Make sure the batteries are
fresh.•
Check if
the
batteries are inserted in
the
correct
direction.•
Check
if
all four
wires
are touching
the correct
metal terminal.If
the
Wind Racer moves
backwards:•
The propeller
is
turning
the
wrong
way.
Remove
the
terminal
caps, change
the wire connections to match the
diagram
in
step 8,
and reinsert the terminal
caps. This
will make the
propeller
turn
in the
opposite direction.If your Wind Racer
does not
run
in a
straight
line:•
Loosen
the screws that connect the
pieces,
make
sure
the long axle is inserted evenly into the rear axle support, and then reattach the wheels.
F. HOW IT WORKS
The
batteries
provide
electricity to the
motor,
which
turns
the
propeller
at a
high speed. The propeller
blades force air backwards.
The
laws of
physics
state that
every
force has an
equal
force that
pushes
in the
opposite
direction.
This
means that when the
propeller
pushes the air backwards, the air pushes the propeller forwards. This is the science behind how the Wind Racer moves.
G. FUN FACTS
•
A propeller
has blades that
push
air
along
as it
spins. The
blades are
angled
like a
wedge
to
push
the air more
effectively. The
blades
are twisted
because
they
move much
faster at their
tips
than at their roots.•
Propeller-powered
cars are
very
rare.
A propeller
car called
the
Helica
was made in
France
between
1913
and
1926, but
only thirty were
ever
built.•
In 1934,
a
propeller-powered
car reached the
dizzying speed
of
137
kilometres
per
hour
(85
miles
per
hour).•
Hovercrafts
and
water-skimming
crafts use
huge propellers
that
push
air
(instead
of
propellers
which
push
water) to
generate enough energy
to
speed
away.•
Jet-powered
and
rocket-powered
cars work in a
similar way to the
Wind Racer. They
send out a stream of
gases backwards,
which
push
the car forwards.
The
world
land-speed
record
is held by Thrust SSC, which was powered by two jet engines.
