The electronics in your airsoft gun are crucial to both accuracy and durability. MOSFET (Metal Oxide Semiconductor Field-Effect Transistor) and ETU (Electronic Trigger Unit) are two of the most popular upgrades that can significantly improve performance. Here's a guide to what they do and how to choose the right one.
What is a Mosfet?
A mosfet is an electronic device that protects your trigger switch and provides faster response time.
- Advantages:
- Reduces wear on mechanical parts, especially the trigger switch.
- Increases power to the motor for faster shot response.
- Enables the use of high-performance LiPo batteries without risk of damaging the weapon.
-
How does it work?
A mosfet bypasses the trigger switch and directs the current from the battery to the motor, ensuring less resistance and higher efficiency.
What is an ETU?
An ETU is an advanced device that combines mosfet functionality with additional electronic controls.
- Advantages:
- Allows for customizations such as burst mode and fully adjustable firing rate.
- Active brake function prevents over-rotation of the gears.
- Faster trigger response and increased precision.
-
How does it work?
An ETU controls the entire firing process electronically, eliminating the need for mechanical switches and providing more advanced features.
Which one should you choose?
- Mosfet: Ideal if you want a simple solution to protect the trigger switch and improve shot response. Perfect for players who use high-performance batteries or want to extend the life of their gearbox.
- ETU: Best for players who want advanced features and full control over their weapon's performance. Suitable for high-performance setups like high-speed or DMR.
Installation
- Mosfet: Relatively easy to install if you have basic technical knowledge. Plug-and-play versions are available to make the process easier.
- ETU: Requires more extensive installation and often a specific gearbox compatible with the ETU system.
Advantages and disadvantages
- Mosfet:
- Advantages: Easy to install, cheaper than ETU.
- Disadvantages: Limited features compared to ETU.
- ETU:
- Advantages: Advanced features and full control over the firing mechanism.
- Disadvantages: More expensive and more complicated to install.
When should you upgrade?
If you are using a standard mechanical trigger system and want to protect it or improve performance, you should consider a mosfet. If you want advanced features like burst mode or fully electronic control, an ETU is the best option.
