Specna Arms Super High Torque Dark Matter™ motor (31000RPM) Short Type 2






The Specna Arms Super High Torque Dark Matter™ Motor (31,000 RPM) Short Type 2 is designed for airsoft players and experienced technicians who want to fit their AEG with a powerful and reliable drive system. With a speed of 31,000 RPM, a power output of 157 watts and high-quality neodymium magnets, this motor delivers an excellent combination of pulling power, fast trigger response and efficient performance.
Specna Arms’ Dark Matter™ series has been developed for both performance-oriented players and technicians carrying out high-quality upgrades. Thanks to its balanced performance, this Short Type 2 motor is suitable for powerful builds where both speed and reliability are key.
Designed for powerful performance
When you fit a replica with a heavier spring or internal upgrades, the load on the motor increases significantly. The Super High Torque Dark Matter™ has been specially developed to handle this extra load with ease.
The high torque ensures that the gearbox continues to run smoothly, even with high-powered set-ups. This means you benefit from a consistent firing cycle and an immediate response to every pull of the trigger.
This makes the engine ideal for players looking for maximum reliability without compromising on performance.
31,000 RPM: the perfect balance
With a speed of 31,000 RPM, this engine offers an excellent balance between traditional high-torque and high-speed engines.
You’ll benefit from:
- Snelle trigger response.
- High pulling force.
- Smooth firing cycles.
- Reliable performance under load.
This makes the motor suitable for replicas that need to respond quickly whilst also being able to drive heavy springs.
Powerful neodymium magnets
The performance of this motor is made possible in part by powerful neodymium magnets.
These magnets produce a significantly stronger magnetic field than standard ferrite magnets, enabling the motor to operate more efficiently and generate greater torque.
The benefits of this include:
- More power with every revolution.
- Faster acceleration.
- Improved energy efficiency.
- Less loss of performance during intensive use.
This makes the motor particularly well-suited to demanding AEG builds.
High-quality copper winding
In addition to the powerful magnets, the motor features a high-quality copper winding.
Thanks to copper’s excellent electrical conductivity, the available current is efficiently converted into power. As a result, the motor responds quickly to every trigger pull and continues to perform consistently even during long days of play.
For players who do a lot of semi-automatic shooting or want to build a responsive replica, this is a major advantage.
Suitable for springs up to M190
The Specna Arms Super High Torque Dark Matter™ supports configurations with springs up to M190.
This makes this engine suitable for a wide range of high-performance builds, such as:
- The DMR platform.
- High FPS-upgrades.
- Semi-only replica's.
- Technical builds featuring high-performance internal components.
To ensure optimum reliability, it is important that the other gearbox components are also suitable for this load. These include reinforced gears, a high-quality piston and robust bearings or bushings.
Sturdy metal casing
The motor is fitted with a sturdy metal housing, which provides protection against heat build-up and mechanical stress.
With an output power of 157 watts, the motor has more than enough power to drive even heavy configurations smoothly.
This robust construction also helps to ensure a long service life, even with intensive use.
Short Type 2 version
This version is a Short Type 2 engine.
Short-type motors are used in various popular airsoft platforms, including:
- AK replicas.
- The G36 platform.
- SIG series replicas.
- Various compact AEGs that use a Short Type motor.
Always check which engine type your replica requires before purchasing a new engine. Many M4 platforms actually use a Long Type engine.
Practical insights
Many players focus solely on an engine’s revs, whereas it is actually the available torque that determines the performance of a powerful AEG.
With 31,000 RPM, this Super High Torque engine delivers an excellent balance between speed and pulling power. This makes the replica feel responsive in semi-automatic mode, whilst the engine continues to perform reliably even under heavy load.
For experienced airsoft technicians, this motor is an excellent choice for high-quality builds where both power and durability are important.
