4. Setup

The ARRMA Limitless V2 is a "roller" model, meaning it comes pre-assembled as a chassis but requires additional electronic components to be fully operational. This allows for complete customization of your power system to achieve desired performance levels.

4.1 Required Components (Not Included)

To get your Limitless V2 running, you will need the following:

• Batteries: Two (2) compatible LiPo batteries (e.g., 4S or 8S total for high-speed running).
• Charger: A compatible LiPo battery charger.
• Electronic Speed Control (ESC): An 8S capable ESC for optimal performance.
• Motor: A powerful brushless motor (e.g., 1717 1650KV for extreme speeds).
• Pinion Gear: Appropriate pinion gear for your chosen motor and desired speed.
• Receiver: A radio receiver compatible with your transmitter.
• Servo: A high-torque steering servo.
• Transmitter: A 2-channel (or more) radio transmitter.

6. Maintenance

Regular maintenance is crucial for the longevity and performance of your ARRMA Limitless V2. After each run, especially high-speed sessions, inspect the following:

• Cleaning: Remove dirt, dust, and debris from the chassis, suspension components, and motor/ESC. Use a soft brush or compressed air.
• Screws and Fasteners: Check all screws and fasteners for tightness. Vibrations from high speeds can loosen them.
• Drivetrain: Inspect the drive shafts, gears, and differentials for wear or damage. Lubricate moving parts as recommended in the detailed product manual.
• Suspension: Check shocks for leaks and ensure smooth operation. Inspect suspension arms and linkages for cracks or bends.
• Tires: Examine tires for wear, punctures, or separation from the wheels. Ensure they are properly inflated (if applicable).
• Electronics: Verify all electrical connections are secure. Check for any signs of overheating on the motor or ESC.
