Setup Guide
Follow these steps to prepare your Serpent X20 for its first use.
1. Unboxing and Initial Inspection
Carefully remove all components from the packaging. Inspect the car and remote control for any visible damage. Ensure all parts listed in "What's in the Box" are present.

2. Applying Decals (Optional)
The included sticker sheet allows for personalization of your RC car. Carefully peel and apply the desired decals to the car body.

3. Battery Installation
Remove the car body by detaching the body clips. Install a fully charged LiPo battery (not included) into the designated battery compartment. Secure the battery with the provided straps or holders. Connect the battery to the Electronic Speed Controller (ESC).

4. Remote Control Setup
Install batteries into the remote control. Power on the remote control first, then the car. Ensure the remote and car are properly bound. Adjust the trim settings on the remote control for steering and throttle as needed to ensure the car remains straight and stationary when the controls are neutral.

5. Pre-Run Checks
Before each run, check the following:
- Ensure all screws are tight.
- Verify battery charge levels in both the car and remote.
- Check tire condition and ensure they are securely mounted.
- Test steering and throttle response.
- Inspect the suspension for proper movement and damping.

Operating Instructions
Operating your Serpent X20 is straightforward, but practice is key to mastering its performance.
- Power On: Turn on the remote control first, then the RC car.
- Driving: Use the steering wheel on the remote for direction and the trigger for throttle (forward) and brake/reverse.
- Speed Control: The brushless motor provides significant power. Start with gentle throttle inputs to get accustomed to the car's speed and handling.
- Turning: Practice smooth turns. The car's enhanced suspension allows for precise handling.
- Braking/Reversing: Push the trigger forward from neutral to brake, then push again for reverse.
- Power Off: Always turn off the RC car first, then the remote control.
