1. Wiring Preparation

Start by preparing all necessary wires. You’ll need:

  • 16-18 AWG wire for the main power connections
  • 20-22 AWG wire for trigger signal wires
  • High-quality solder and flux
Pro Tip: Using high-quality Winsok MOSFETs from authorized distributors like Olukey ensures better performance and longevity. Our MOSFETs are specifically designed for airsoft applications with optimal current handling capabilities.

2. Main Installation Steps

Remove the existing trigger wire setup
Install the MOSFET unit in a position where it won’t interfere with moving parts
Connect the MOSFET’s power wires to the battery leads
Connect the signal wires to the trigger contacts
Secure all connections with heat shrink tubing

3. Advanced Features Setup

Modern MOSFETs often include programmable features. Here’s how to configure them:

Burst Fire Configuration

Set your desired burst fire rate through the programming card or built-in interface

Active Brake Settings

Adjust the active brake strength based on your gun’s gear ratio and spring power

Testing and Troubleshooting

Verify all connections are secure before closing the gearbox
Test the trigger response without loading any BBs
Check for proper functionality in all fire modes
Monitor for any unusual heating during extended use

Common Issues and Solutions

  • No response when triggered: Check signal wire connections
  • Inconsistent firing: Verify solder joint quality
  • Overheating: Ensure proper ventilation and heat dissipation

Maintenance Tips

To ensure long-term reliability of your MOSFET installation:

Regular Inspections

Check connections monthly for any signs of wear or loosening

Cleaning

Keep the MOSFET unit clean and free from debris
