[HTG] KURO Gen Motor Long for Electric Guns

[Product Concept]
Easily upgrade the response and rate of fire of your airsoft gun by replacing the standard motor found in foreign-made electric airsoft guns.

[Optimized for 7.4V LiPo Batteries]
Many foreign-made motors are designed to perform optimally with 11.1V batteries, but
the "Gen Motor" is optimized specifically for use with 7.4V LiPo batteries.

[High Speed, High Torque]
This is a balanced, high-power motor that transcends the boundaries of high-speed and high-torque.
We have set the rate of fire to be under 20 rounds per second, which is the limit for electric airsoft guns with standard gear ratios and spring rates,
and maximized torque to improve responsiveness.

[High-Quality Components]
Key components of the motor are made by Japanese manufacturers, pursuing high precision and high efficiency.

[Bearing Supported Shafts]
The long shaft features two high-precision bearings in the main body and two more in the motor tower to reduce friction loss.
*The short shaft has two bearings in the main body.

[High Quality, Low Price]
High quality due to manufacturing by a specialized motor manufacturer, and low cost due to mass production!
We achieved a low price by focusing on specific performance goals.

[Sintered Steel Pinion Gear]
We deliberately chose a sintered steel pinion gear to achieve both wear resistance and strength, second only to machined steel pinions. This choice was made due to the low aggressiveness of hard-cast pinion gears on the bevel gear, their good meshing, and low noise.
Through actual machine testing, we selected a pinion gear with broad compatibility.
Additionally, it uses a commonly available O-axis for easy replacement of the pinion.

*Please remove the protective film on the motor body before use.

Compatibility with foreign-made models and custom gears has been confirmed through actual machine testing.

Airsoft Guns:
DE Airsoft/WellPro/Golden Eagle/LCT/G&G/VFC/CYMA/S&T/SPECNA ARMS/E&C/ARCTURUS/C.A.T/DMT/etc.

Custom Parts:

Actual Firing Test Results
Test machine: DE Airsoft PDX
Chronograph: ACE TECH AC6000 BT
Power supply: KIKUSUI PWR801
Output setting: 8.4V 80A (assuming 7.4V LiPo battery)
Normal 13.5rps → Gen Motor 19.8rps
The rate of fire has significantly increased.
Since the torque and rotation speed are set to achieve approximately 20 rounds per second with standard 18:1 gears,
the gearbox will perform like a custom gun even if it's stock.
*Values may vary slightly when using a battery.

[Please Note]
・Disassembly of the electric airsoft gun is required for installation.
・Although developed for wide compatibility, gear noise may occur due to compatibility with the main body.
Replacement of the bevel gear or shim adjustment may be necessary.
・If the included motor tower spring does not fit, please replace it with the original one.
・For models that use special-shaped springs for short-shaft motors (e.g., G36, Steyr), please use the spring included with the main unit.
・For models with small motor holes in the grip (e.g., G&G), it may be necessary to enlarge the hole to allow the pinion gear to pass through.
・If the muzzle velocity decreases during full-auto firing compared to semi-auto, adjustment within the gearbox may be necessary.
