-
The version and mosfet choice are up to you. Experienced techs who prefer to do their own wiring may prefer the BASE version. The PRO is good for those who want the best of the best in their guns.
-
Yes! The Warhead brushless motors go great with the M-Trigger for top-tier performance. Any of the mosfets listed here are compatible, just be sure to turn off any rate of fire control and use the minimum amount of active braking.
-
No, we do not give or sell the 3D files. We’ve perfected the M-Trigger through years of effort and believe you will get the best quality and performance if we make it for you. Plus, the sales of M-Triggers allow us to continue operating as a small business to create even more new products.
-
A hardwired mosfet is required for the M-Trigger to work. You cannot use plug and play mosfets that just go in between the wiring and battery. If you choose to use a mosfet not listed here, we cannot guarantee functionality. Your mosfet must have a debouncing function in order to work with the microswitch.
-
Very easy. Everything you need is included in the LITE and PRO versions. Simply remove your gearbox from the back of the gun, swap out the trigger units with a screwdriver, and attach the wires to the motor. That’s it!
-
No, the M-Trigger will significantly improve the performance even on 100% stock guns. For the best trigger response, we do recommend an upgraded motor and lipo battery, but this is completely optional.
