The highly popular HAIBOXING 3100A RC CAR has finally received its brand-new third-generation upgraded version.

This rear solid axle short course truck has been one of the hottest-selling models for a long time, often going out of stock. Now, the latest generation keeps the classic rear axle design while bringing major improvements in durability, handling, and overall driving experience.

For RC enthusiasts who enjoy realistic short course truck dynamics, rear-wheel-drive handling, and aggressive sliding action, this upgraded version is definitely worth paying attention to.

1. The Rear Solid Axle Design Is Still the Biggest Highlight

The core feature of the HAIBOXING 3100A RC CAR is its rear solid axle structure.

Compared to independent suspension setups, this design creates a much more realistic short course truck driving posture. During acceleration, cornering, and rough terrain driving, the rear axle movement is very noticeable, making the truck behave more like a real off-road racing truck.

This is exactly why the 3100A has remained so popular among RC fans.

The third-generation version also upgrades the rear drivetrain with a thicker metal rear driveshaft, significantly improving durability and impact resistance compared to previous versions.

For drivers who enjoy jumping, bashing, and aggressive driving, this upgrade makes the truck feel much more reliable.

2. The Third-Generation Upgrade Brings a More Complete Setup

Besides the rear axle improvements, the third-generation HAIBOXING 3100A RC CAR also receives several upgrades throughout the vehicle.

The truck now includes an upgraded cooling system to help reduce heat buildup during extended high-speed driving sessions.

The suspension uses fully adjustable oil-filled shocks, helping absorb impacts more effectively while allowing tuning for different terrain conditions.

Several important structural components are also upgraded to metal parts, including:

• Steering links
• Front and rear driveshafts
• Differential components

These upgrades greatly improve overall durability compared to standard plastic setups.

3. The Brushless Power System Makes It More Fun for Aggressive Driving

The HAIBOXING 3100A RC CAR is equipped with a brushless motor system.

Compared to brushed setups, brushless power delivers stronger acceleration and much better high-speed performance.

The truck comes standard with a 2S battery and officially supports up to 3S power.

For casual driving, 2S already feels quick and responsive. Once upgraded to 3S, however, the truck becomes much more aggressive, with stronger acceleration and more dramatic rear-end sliding behavior.

The vehicle also includes a built-in integrated gyro system, helping maintain stability during high-speed driving and drifting.

Another nice touch is the inclusion of two replaceable spare tires, which not only improve realism but also give the truck a more authentic off-road racing appearance.

4. The Type-C Rechargeable Transmitter Is a Very Practical Upgrade

One of my favorite upgrades on the new HAIBOXING 3100A RC CAR is the transmitter.

The controller now uses a built-in Type-C rechargeable battery system.

That means:

You no longer need AA batteries.

You can simply charge the transmitter using a regular phone charging cable, making daily use much more convenient.

The package also includes the original charging cable, body clips, and decorative stickers right out of the box.

5. The Driving Feel Is Still the Soul of This Truck

The handling experience is honestly one of the biggest reasons why so many people like the HAIBOXING 3100A RC CAR.

The truck supports full proportional throttle and steering control, making low-speed corrections and high-speed drifting feel much smoother and more precise.

The power switch is conveniently placed on the rear side of the body, so you can turn the truck on or off without removing the body shell.

Binding the transmitter is also very simple:

Just hold the pairing buttons on both the transmitter and vehicle until the connection tone finishes.

Once you start driving, the rear solid axle behavior becomes extremely noticeable.

Especially on dirt, sand, or asphalt surfaces, the rear suspension movement and sliding posture create a very realistic short course truck driving experience — something many independent suspension RC cars cannot fully replicate.

6. Is the HAIBOXING 3100A RC CAR Worth Buying?

If you enjoy:

• Rear-wheel-drive short course truck handling
• Realistic suspension movement
• Aggressive drifting and sliding
• Brushless high-speed performance
• Future 3S upgrade potential

then the third-generation HAIBOXING 3100A RC CAR is definitely a very interesting option.

Its biggest strength is not simply raw top speed.

Instead, it delivers a much more mechanical and realistic driving experience, especially thanks to the unique rear solid axle setup that gives the truck its signature personality.
