Setup Guide

1. Battery Installation and Charging

1. Ensure the vehicle's power switch is OFF.
2. Remove the body clips and lift the body to access the battery compartment.
3. Insert a fully charged Traxxas Power Cell NiMH or LiPo battery into the battery tray. Secure it with the battery strap.
4. Connect the battery to the Electronic Speed Control (ESC).
5. Reattach the body and secure it with the body clips.
6. Charge your battery using a compatible Traxxas charger according to the charger's instructions. Always supervise charging.

2. Transmitter Setup

1. Install four AA batteries into the TQi 2.4GHz transmitter.
2. Turn on the transmitter. The status LED should glow solid green.
3. Turn on the vehicle's power switch. The ESC LED should glow solid green, indicating a successful connection.
4. If the transmitter and receiver do not link, refer to the binding instructions in the TQi transmitter manual.

3. Initial Checks

• Verify steering response: Turn the steering wheel on the transmitter; the front wheels should turn accordingly.
• Check throttle response: Gently pull the throttle trigger; the vehicle should move forward. Push the trigger forward for reverse.
• Ensure differential lock and high/low range shifting function correctly using the auxiliary switches on the transmitter.

Operating Your TRX-4 Defender

Driving Tips:

• Throttle Control: Use smooth, gradual throttle inputs for precise control, especially on technical terrain.
• Steering: Practice steering at various speeds to get a feel for the vehicle's response.
• Terrain Awareness: Always observe the terrain ahead and plan your lines to avoid obstacles and potential rollovers.

High/Low Range Transmission:

The TRX-4 Defender features a two-speed transmission that can be shifted remotely from your transmitter. Use the designated switch (typically a 2-position switch) to toggle between high and low gears.

• Low Range: Provides maximum torque and control for climbing steep inclines, navigating technical rock sections, and slow-speed crawling.
• High Range: Offers higher speed for traversing flatter terrain and covering longer distances.

Remote-Locking Differentials:

The front and rear differentials can be locked independently or together using the auxiliary switches on your transmitter. Locking differentials provide maximum traction by ensuring both wheels on an axle receive equal power, which is crucial for extreme off-road conditions.

• Unlocked: Allows wheels to spin at different speeds, improving turning radius and handling on less challenging terrain.
• Locked: Provides superior traction on slippery or uneven surfaces, enabling the vehicle to pull itself over obstacles.

Maintenance

Regular maintenance is crucial for the longevity and performance of your TRX-4 Defender. Follow these guidelines:

After Each Use:

• Cleaning: Remove dirt, mud, and debris from the chassis, suspension, and drivetrain using a soft brush or compressed air. Avoid using water directly on electronics unless specified as waterproof.
• Inspection: Check for any loose screws, damaged parts, or worn tires. Tighten fasteners as needed.
• Battery Care: Disconnect and remove the battery. Store it in a cool, dry place according to battery manufacturer recommendations.

Periodic Maintenance:

• Lubrication: Apply a small amount of silicone shock oil to the shock shafts and inspect the gears for proper lubrication.
• Suspension: Check the shocks for leaks and ensure smooth operation. Replace worn shock oil or O-rings if necessary.
• Drivetrain: Inspect the driveshafts, axles, and differentials for wear or damage.
