O’DONNELL HISTORY

Every dream has a beginning and an end. This one just happened
to start out in the O’Donnell family garage back in 1980. Young
Steve O’Donnell wasn’t satisfi ed with the mediocre products
that the RC industry had to offer, so he set out to build the best
engineered and manufactured products available. Lucky for us, his
dream is far from over…

O’Donnell took his vast knowledge of nitro engine tuning and soon
designed products that would complement his talents. First came
his custom designed and machined aluminum cooling heads for
the on-road racing scene. Finding another void in the industry, he
also began producing custom tuned pipes to better utilize all of the
power these nitro burning monsters could produce.

The efforts of O’Donnell did not go overlooked. Some of the major
R/C manufacturers went to O’Donnell Manufacturing to have their
trick aluminum parts machined. O’Donnell’s meticulous standards
and overwhelming knowledge of the products made it a natural fi t.
Over the past 24 years, O’Donnell Manufacturing has produced parts
for such notable companies as Team Associated and Team Losi.

O’Donnell Manufacturing took another major step forward in 1988
when they introduced O’Donnell Racing Fuel…the name that
made them famous with racers around the world. Once again,
O’Donnell saw a need — for a high-quality fuel specifi cally blended
for the demands of nitro burning car engines. From that point on,
O’Donnell Racing Fuel became synonymous with winning. To this
day, no other fuel has won as many national championships as
O’Donnell Racing Fuel.

Not afraid to take chances on long shots, in 1999 O’Donnell spotted
a little kid from the hills of California who had a great deal of driving
talent. This kid would later become a National Champion in both
electric and nitro. He would also go on to TQ and win the IFMAR
World Championships. That kid was the one and only Jared Tebo.
The name Tebo quickly became associated with O’Donnell and
winning. He’s known around the world for his race-winning talent.

O’Donnell’s dreams moved to the next level when he embarked
on the ultimate journey…the design and creation of a new 1/8
off-road nitro racing buggy. The plan was simple: Don’t try to “re­invent the wheel”, just refi ne it…all of it.

Now, after extensive development, refi nement, testing, and on­track race-winning results, we are proud to introduce the Ultimate
Racing Machine –

Designed by O’Donnell, Tested by Tebo….the Z01-B.

To complement the racing fuel, O’Donnell set out in 2000 to design
a glow plug that would out-perform and out-last all the competitors.
The result? Two U.S. patents and a World Championship. Not
bad for someone who started out in his parents’ garage. Today,
O’Donnell glow plugs are the choice of champions worldwide.

SAFETY PRECAUTIONS

Use care and good sense at all times when operating this radio
controlled buggy. Failure to use this vehicle in a safe, sensible
manner can result in injury or damage to property. You and you
alone must insure that the instructions are carefully followed and
all safety precautions are obeyed.

• Do not operate the Z01B near people. Spectators should be
behind the driver or at a safe distance away from the vehicle.

• Water can cause the electronics to short out and can cause
permanent damage.

• Always turn on the transmitter before turning on the receiver.

• Fully extend the transmitter antenna before operating your vehicle.

• Before turning on your radio system, check to make sure that no
one else is running on the same frequency.

• The engine and exhaust produce quite a bit of noise. Do not run
this vehicle when or where it can disturb others.

• The engine and exhaust can become very hot. Avoid touching
any of these parts during use and until they have cooled down.

• Model engine fuel is poisonous. Make sure you read and follow
all of the precautions on the fuel container. Keep fuel out of the
reach of children.

• Model engine fuel is fl ammable and when ignited has a fl ame
that is diffi cult to see. Avoid sparks, fl ames, smoking, or any
other ignition source when fuel is near.

• The engine emits harmful fumes just like real vehicles. Do not
operate this model indoors.

• Avoid running the buggy in cold weather. The plastic and metal parts
can become brittle at low temperatures. In addition, grease and oil
become thick, causing premature wear and poor performance.

iv

• Read the instructions carefully before starting assembly.

• We recommend building the kit on a towel to help prevent small parts and screws from rolling off your work surface.

• Before turning on your radio system, check to make sure that no one else is running on the same frequency.

• Do not use an electric screwdriver/drill for assembling the kit. This could cause parts to strip out from overtightening.

• Use a quality threadlock where specifi ed in the manual.

• Parts for step included in this parts bag.

• Apply grease to part(s) indicated. Note: Always use black moly grease on areas indicated.

• Apply threadlock to screw(s) indicated. IMPORTANT: Clean oil or fi lm from screws before applying threadlock.
