When building a small underwater robot, remotely operated vehicle (ROV), or RC boat, choosing the right propulsion system is often a challenge.

A large thruster may provide more power, but it also increases weight, power consumption, and installation difficulty.

For compact projects, efficiency and size are often more important than maximum thrust.

This is where the APISQUEEN X2 Micro Underwater Thruster comes in.

Designed for small underwater applications, the X2 combines a lightweight structure, efficient brushless motor, and practical thrust output, making it an ideal propulsion solution for ROVs, RC boats, autonomous boats, and DIY marine projects.

Compact Design, Powerful Performance

The biggest advantage of the X2 is its compact size.

With a weight of only 117g, the X2 is designed for applications where every gram matters.

Small underwater robots and RC vessels often have strict limitations on space and payload. A lightweight propulsion system helps maintain better balance while reducing the overall load on the platform.

Despite its small size, the X2 delivers up to:

• 2.1kg maximum thrust
• 224W maximum power
• 84W continuous power

This makes it a practical choice for small-scale underwater propulsion applications.

Efficient Brushless Motor Technology

The X2 uses an outer rotor brushless DC motor, providing excellent efficiency and smooth power delivery.

Compared with traditional brushed motors, brushless motors offer:

• Higher efficiency
• Lower maintenance requirements
• Longer service life
• More stable operation

With a 830KV motor, the X2 provides a balanced combination of speed and torque, making it suitable for compact underwater vehicles that require reliable propulsion.

Low Power Consumption for Longer Operation

The X2 operates at 12–16V (3–4S LiPo battery), making it easy to integrate into many small electronic platforms.

Its efficient design allows users to achieve a good balance between thrust performance and energy consumption.

With:

• Maximum current: 15A
• Continuous working current: 7A

the X2 is suitable for projects where battery capacity and operating time are important considerations.

3D Printed ABS Housing: Lightweight and Customizable

The X2 uses a 3D printed ABS housing, providing a lightweight and practical structure for DIY applications.

ABS material offers:

• Good impact resistance
• Lightweight construction
• Easy customization

For makers and developers, the 3D printed design also provides flexibility for prototype projects and custom applications.

In addition, the thruster housing and propeller colors can be customized.

If you require a specific color combination, please leave a note when placing your order.

Recommended ESC Options

To achieve the best performance, the X2 is recommended to work with:

• Feather 30A ESC (with 5V BEC output)
• Feather 45A ESC (without BEC output)

The correct ESC selection ensures stable motor control and reliable operation.

Ideal Applications

The X2 is designed for a wide range of small underwater applications, including:

Underwater Robots (ROV)

For ROV projects, size and efficiency are critical.

The X2 provides a compact propulsion solution that can help small underwater robots achieve stable movement and precise control.

RC Boats

For hobbyists building custom remote-controlled boats, the X2 offers a lightweight and efficient power option.

Its compact size makes installation easier while still providing enough thrust for small platforms.

Autonomous Surface Vehicles

For small unmanned boats and experimental platforms, the X2 provides reliable propulsion without adding unnecessary weight.

DIY Marine Projects

Whether you are a student, engineer, or hobbyist, the X2 is suitable for various creative underwater projects.

Its compact design allows it to be integrated into different custom platforms.

Why Choose the APISQUEEN X2?

The X2 is designed around three key principles:
