XO-1

EXPERTS ONLY: OPERATING THE XO-1 AT MAXIMUM SPEED

Now that you are familiar with the operation of the XO-1 in ‘out-of-
the-box’ trim, it’s time to explore the upper limits of its performance
capability.

Before you unlock the power system and outfit your model

for full-power operation, make certain you have fully read and
understand the warnings and precautions starting on page 3

If you have questions about the XO-1, please contact Traxxas at
1-888-Traxxas or e-mail us at [email protected]

Installing the High-Speed Pinion

1. Remove the right rear wheel. This will make it easier to adjust the

gear mesh.

2. Remove the right rear shock’s upper mounting screw and pivot it

away from the chassis to allow clearance for the pinion when you
remove the motor.

3. Remove the 3x8mm cap screw and lift the motor cooling duct off

the chassis.

4. Remove the 3x15mm cap screws and slide the motor out of the

motor mount. You do not need to unplug the motor from the
speed control or remove the motor temperature sensor.

5. Loosen the 4x4mm set screw in the pinion and slide the pinion off

the motor’s output shaft.

6. Install the high-speed pinion on the

motor’s output shaft. Do not tighten
the set screw yet.

7. Turn the shaft so the pinion’s set

screw faces up. With the 2mm
driver installed in the pinion’s set
screw, slide the pinion toward
the motor mount until the
driver fits into the slot in

the motor mount. This sets the pinion’s offset from the motor for
proper mesh with the spur gear. Tighten the set screw.

8. Reinstall the motor and cooling duct. Follow the steps on

page 20 to properly set the gear mesh.

Installing the 100mph Splitter

The 100mph splitter with canards is required for 100mph running.
DO NOT run the XO-1 at 100mph without the splitter. It provides
downforce and stability. Failure to install the 100mph Splitter may
result in a loss of control at high speed.

Remove the two 3x10mm countersunk screws and the center
4x15mm countersunk screws that attach the splitter extension to
the splitter mount. Loosening the two outer 4x15mm countersunk
screws attaching the front body mount to the splitter mount
will aid in removing the splitter extension. Remove the splitter
extension and store it with the other accessories for your model.
Install the 100mph splitter extension and reinstall the 3x10mm and
4x15mm screws. Retighten the outer 4x15mm screws to complete
the installation.

Unlocking the Power System for 100mph Running

The XO-1 is ‘locked’ to limit its top speed to 50mph. To access the
model’s full power capability and 100+mph top speed, you must
‘unlock’ the power system. This requires an internet-enabled Apple
iPhone

or iPod Touch,

the Traxxas Link application (available in the

Apple App Store), and a valid e-mail address that you can access.

Follow the steps below to unlock the speed control:
1. Install an internet-enabled Apple iPhone or iPod Touch in the

Docking Base included with the TQi transmitter. Instructions on
installing your mobile device follow.
