Assembly Instruction & Parts List

Precautions
Precautions With Small Children
• For children under the age of 13, parental guidance
is recommended when running.
Assembly Precautions
• Choking hazard. Do not assemble near small children.
• Check the contents carefully before assembly. Please
contact Customer Service at: 1.800.345.4545 if you
have any defective or missing items.
• Carefully read through this manual, and familiarize
yourself with the instructions.
• Many different tools are required during assembly.
For safety purposes, please use the correct tools.
• Exercise caution when using sharp tools such as a
hobby knife.
• Many different materials are used in the construction
of these parts. Use extra care when handling parts
with sharp edges, such as machined metal parts.
• When cutting plastic parts, watch for any ying parts.
• Try to assemble any rotating parts or drivetrain parts
as carefully as possible.
• Bundle wires neatly away from the ground or any moving
drivetrain components. Make sure that all wires are
securely connected to prevent electrical shorting.
• Unnecessary modications may be unsafe and hinder
performance.
Precautions Before Running
• Some models may exceed speeds of 25 mph. Prac-
tice common sense and run the Stinger in open safe
places, or R/C car tracks.
• Do not run the Stinger on public roads with high
amounts of trafc, or in areas that may cause an
inconvenience to people in that area.
• The Stinger is controlled using a radio frequency.
Radio interferences may cause loss of control.
• If others near you are running R/C cars, conrm that
they are not running on the same frequency.
• This unit is manufactured with waterproof electronics,
but it should not be submerged in water for extended
periods of time.
• The drivetrain of the Stinger consists of many moving
parts like gears, shafts, and tires. Avoid touching these
areas when the battery is connected.
• Many parts of the Stinger will become hot after
running. Allow the parts to sufciently cool before
conducting any maintenance.
Beginning a Run
1. Place the Stinger so that the wheels are off the ground.
2. Conrm that the speed controller switch is OFF, and
connect the motor and battery.
3. Switch the transmitter ON. (Do not use the transmitter
with low voltage. Ensure that the transmitter batteries
are good before use.)
4. Turn the speed controller switch ON.
Ending a Run
1. Turn the speed controller switch OFF.
2. Disconnect the battery.
3. Turn the transmitter switch OFF.
Battery Usage
(Carefully read the instruction included with the batteries.)
• When charging batteries, ensure nothing ammable
is in the surrounding area. Also avoid charging in
high-temperature locations.
• After use, allow the battery to cool before charging.
• When charging batteries, be sure to frequently monitor
the battery. Unattended, it could pose a re hazard.
• If the battery reaches 122º F or more, stop charging.
• Batteries will become hot after running. Continuous
use of the battery pack may result in damage to
the cells. Allow the battery too cool down before
re-charging. Using a battery conditioner after running
may prolong the life and performance of the battery.
• Please do not discard old battery packs in the trash.
Locate a battery disposal center.
Motor Usage
• Connecting a 7.2V battery directly to the motor can
be very dangerous.
• Choose the appropriate gear ratio that matches the
motors power characteristics.
• Using a gear ratio not suited to the characteristics
of the motor will not only prevent the motor from
performing at its optimum, but may damage the
other electronics.
• Motors will generally become very hot after running.
Continuous running will reduce the life of the motor.
Allow the motor to sufciently cool between each run.

Slipper Clutch System
The base factory setting is a starting point to allow
enough slippage to protect your drivetrain from heavy
throttle loads.
Do not set the slipper clutch too tight as this may damage
the transmission. If set too loose, the Stinger will have a
lack of performance which may result in damaging the
slipper clutch system.
Recommended Slipper Clutch Adjustment:
• First, place the 2.0mm Allen wrench tool (included)
into the center drive cup horizontally through the drive
cup where the dog bone pin sits and hold by hand to
lock the transmission.
• Second, tighten the slipper adjustment nut in a clock-
wise rotation by using 7mm hex driver or the 4-way-
tool (included) until it stops then loosen it counter-
clockwise by 1 turn.
• Once the initial adjustment has been done, tighten or
loosen your slipper no more than 1/8of a turn at a
time and test again to obtain your optimal slippage for
your application.
