Before first use, carefully inspect the vehicle for any signs of damage that may have occurred during shipping. Ensure all screws are tight and moving parts operate freely.

4.2 Battery and Charger (Sold Separately)

The Traxxas Maxx 4S V2 requires a 4s LiPo battery and a compatible LiPo charger. Refer to the battery and charger manuals for their specific operating instructions and safety guidelines. Always use a LiPo-compatible charger and follow all safety precautions when handling LiPo batteries.

  • Battery Installation: Securely install the charged LiPo battery into the battery compartment. Ensure the battery is properly connected to the VXL-4s ESC.

4.3 Radio System Setup

The TQi 2.4GHz radio system is pre-bound to the vehicle. If re-binding is necessary, consult the TQi radio system manual for detailed instructions.

  • Transmitter Batteries: Install four AA batteries into the TQi transmitter.
  • Power On Sequence: Always turn on the transmitter first, then the vehicle. When finished, turn off the vehicle first, then the transmitter.

The Maxx 4S V2 features a clipless body mount system. Align the body over the chassis and press down firmly until it clicks into place. To remove, pull up on the body release tabs.

5. Operating Instructions

5.1 Driving the Vehicle

Once the battery is installed and the radio system is powered on, the vehicle is ready for operation. Use the steering wheel on the transmitter to control direction and the trigger to control throttle (forward/reverse).

  • Traxxas Stability Management (TSM): TSM assists in maintaining control on slippery surfaces, allowing for faster acceleration and braking. Adjust TSM sensitivity via the multi-function knob on the transmitter.
  • Self-Righting: If the vehicle flips over, activate the self-righting feature (refer to the TQi manual for specific button assignment) to return it to an upright position without manual intervention.
  • Speed: The Maxx 4S V2 is capable of speeds exceeding 55 MPH with a single 4s LiPo battery. Optional gearing can further increase top speed to over 60 MPH.
