Gearing for 50+mph
The included “High Speed” pinion gear will allow your model to
reach 50+mph when used with an additional Power Cell Series 1
battery (Part #2925) and (Part #3063) series connector (battery and
series connector sold separately).
50+mph Pinion Installation Instructions
1. Remove the motor as described in
Motor Installation (following)
.
2. Use the supplied 1.5mm wrench to loosen the pinion’s set screw.
Remove the stock pinion.
3. Place the high speed pinion gear onto
the motor shaft. Align the set screw
hole with the flat side of the shaft.
4. Thread the supplied 1.5mm set screw
into the high speed pinion gear but
do not tighten it yet.
5. Slide the pinion gear down the motor
shaft so the wrench shaft fits into the
notch in the motor mount, as shown.
Tighten the set screw.
To complete the installation, reinstall the motor and set the gear
mesh as described to the right. Make certain the pinion does not
contact the motor mount or motor plate.
50+mph Battery Installation Instructions
1. Install the supplied battery as described on page 12.
2. Install an identical Power Cell Series 1 battery (#2925) sold
separately) in the opposite battery compartment.
3. Plug both batteries into the Y-harness (sold separately). The
harness connects the two packs in series. The two 7.2-volt 6-cell
battery packs will operate as one 14.4-volt 12-cell battery pack.
4. Plug the Y-harness into the speed control.
Motor Installation
To access the
motor, remove
the gear cover by
removing the single
screw on the top
of the gear cover.
The motor uses an
aluminum mount
for quick, easy
motor access and gearing adjustment.
To remove the motor, first open the
right battery door and slide out the
ESC. Next, remove the single large
hex screw using the supplied 2.5mm
wrench. Then rotate the motor and
mount to the side of the model, and
slide backward off the post.
The motor mount was carefully
engineered to provide additional
features and adjustability. Two sets of
holes are provided for use with brushed
and brushless motors. The holes for
brushed motors are spaced 16mm
apart and accept 2.5mm screws. The
holes for brushless motors are spaced
19mm apart and accept 3mm screws.

Battery Precautions
•
Make certain both batteries are fully charged before
installing them in your model. Installing a fully charged
pack and a partially discharged pack may lead to
overdischarging and damage to the partially discharged
battery.
•
Do not mix batteries of different brands, chemistries or
capacities. Only genuine Traxxas batteries are approved
for dual-battery use in this model.
•
The high speed dual-battery and gearing configuration
is for high-speed running on smooth surfaces only. Avoid
repetitive hard acceleration to prevent overstressing the
motor, speed control and batteries. Stop running your
model and allow it to cool if the speed control’s thermal
overload protection activates or if the motor temperature
exceeds 200° F. Failure to install the appropriate gearing
can cause failure of the motor, speed control and batteries
when running the model on 12 NiMH cells.
