4. Setup
4.1 Battery Installation and Charging
The UDIRC 1610S comes with a 2400 mAh 3S LiPo battery. Ensure the battery is fully charged before first use. Connect the battery to the provided charger and plug the charger into a compatible USB power source. The charger's indicator light will show charging status (e.g., red for charging, green for fully charged).
To install the battery in the vehicle, secure it in the designated battery compartment using the Velcro strap. Ensure all connections are firm.
4.2 Transmitter Setup
The Dumbo Pro 2.4GHz radio system provides precise control. Install 4 AA batteries (not included) into the transmitter. Turn on the transmitter before turning on the vehicle. The transmitter features trim adjustments for steering and throttle, allowing you to fine-tune the vehicle's handling.
4.3 ESC Programming
The 60A ESC is programmable, allowing you to customize various parameters to match your driving style and track conditions. An optional ESC programming card (sold separately) can be used to adjust settings such as throttle response curve, braking power, drag brake intensity, and low-voltage cutoff.

4.4 Light Installation
The UDIRC 1610S comes with LED lights for enhanced visibility. To install the lights, carefully route the wires and connect them to the designated ports on the receiver. Ensure the connections are secure to prevent dislodging during operation.
5. Operating
5.1 Basic Controls
Turn on the transmitter first, then the vehicle. The transmitter's steering wheel controls direction, while the trigger controls forward/reverse movement and braking. Familiarize yourself with the controls in an open area before attempting high-speed maneuvers.
5.2 Driving Modes
The programmable ESC allows for different driving modes, including a racing mode and a backflip mode. These modes can be configured using the optional ESC programming card to optimize performance for various stunts or racing conditions.

5.3 Self-Righting Function
The UDIRC 1610S features a self-righting function, allowing the vehicle to flip itself back over after an overturn without manual intervention. This is achieved by quickly accelerating and then braking to use inertia to correct its orientation.

6. Maintenance
6.1 General Care
Regularly inspect your RC car for any loose screws, damaged parts, or debris. Clean the vehicle after each use, especially after running in dirt or wet conditions, to prevent buildup and ensure smooth operation. Store the vehicle in a dry, cool place away from direct sunlight.
6.2 Transmission System
The UDIRC 1610S features a fully CNC-Machined Chromium Steel drive system and a sealed driveshaft system. This robust design minimizes wear and tear, but periodic inspection of gears, universal driveshafts, and differentials is recommended. The quick-release design allows for easy access to the drivetrain and differentials for maintenance.

6.3 Shocks and Suspension
The independent suspension system features aluminum oil-filled shocks. Regularly check the shocks for leaks or damage. Adjust spring preload to modify ride height and ground clearance, and ensure proper oil levels for optimal damping.

7. Troubleshooting
If the vehicle exhibits abnormal behavior, stops responding, or experiences any issues, immediately stop operation and check for the following:
- Battery Level: Ensure the vehicle and transmitter batteries are fully charged.
- Connections: Verify all electrical connections are secure and free from damage.
- Obstructions: Check for any debris or foreign objects obstructing moving parts.
- Damage: Inspect for any visible damage to components such as gears, driveshafts, or suspension.
- Binding: Ensure all moving parts operate freely without binding.
If issues persist after basic troubleshooting, refer to the detailed troubleshooting section in the full instruction manual or contact UDIRC customer support.
