    Hello airsofters
    I'm trying to decide on a mosfet for my recently purchased ICS Mars cxp rifle. Trigger response isn't great in semi. I've been looking at the warfet. Mostly for the pre cocking feature. Does anyone have experience with the warfet or other precocking mosfet?

    I'm mainly looking for faster trigger response and less pull.

    Or is there a better way to achieve better trigger response? This is all new to me. Any help would be greatly appreciated

    I would get a Gate TITAN and a Maxx speed trigger or a Titan speed trigger.

    Ok….I don’t know what the mosfet is for. Most of my guns are GBB, and HPA. I have two AEGs right now. One is over 10 years old, and the other is an AK, both of witch don’t have mosfets.

    What’s the mosfet supposed to be doing?

    Battery protection and precocking and other tuning features for the most part

    Ok. So from what I can tell the gate warfet does pretty much everything the titan does except that you use a card to setup rather then an app on your phone. The warfet is about half the cost. Is the titan that much better?

    What can the titan do that the warfet can't?

    The titan is an optical mosfet. The warfet just attaches to your existing wiring.

    A better battery and strong motor can improve trigger response. Which is the foundation "before" adding in a MOSFET into the system.

    Plus can you quantify your desired trigger response improvement levels that you are seeking?

    The job of a MOSFET is to keep that built up carbon on the trigger contacts to a minimum and to keep your trigger contacts from melting when use a LiPo. Now most modern MOSFET units come with the extra features (such as precocking, battery protection, debouncing, programable burst, etc.) built into one board. It is a good addition to any AEG. But if you want trigger response, Guges has a good point; just drop in a nice Tienly or Warhead Base motor and use a good (at least 25c) 7.4 or 11.1 LiPo depending on the RPM Motor you select.

    The perun is also a great budget option if you want features.

    I'm not sure tho what compatability that gearbox has with all these mosfets however

    I love Perun mosfets. Had better luck with them than I did with Gate. Speaking of which, does any of you know if I can use copper wire with the standard wire that comes on a Gate Titan? I need to fix my wire.

    To avoid any compatability issues, the OP can always install a Perun Inline MOSFET, like the AB++.

    The primary job of a MOSFET is to have a solid state switch that can safely snub kickback voltage from an inductive load (motor). It will increase reliability over time as there is no contact arcing/pitting which damages the switch surfaces and increases contact resistance.

    MOSFET components have different ratings and specs in terms of internal resistance and current handling, which can be used to our advantage should we need an application outside of the original Tokyo Marui spec...which is basically any modern competition-use AEG.

    Copper wire as in solid wire? Possible but not recommended, stranded wire is highly preferable for non-stationary installations due to it resisting mechanical stress like bending/vibration better. The only application I could see solid or fewer-stranded wire being necessary is for extremely high current delivery requirements in a compact space (fewer strands means more conductor cross-sectional diameter in a given AWG). However, depending on the MOSFET controller PWM frequency a solid-wire installation may be affected by the skin effect to the point where it drops the conductor impedence to stranded wire levels anyway.

    Oh, no I meant copper stranded wire.

    Vast majority of stranded wire is tinned copper, your main focus would to swap the low strand count Gate wire with higher strand count wire for greater flexibility. Look for RC-grade 'wet noodle' silicone jacket stuff around 18AWG

    The stock wire is 16AWG. Will 18AWG pose a problem?

    Unlikely. Silicone jacket is thicker than the mPPE they use but if the 18AWG wire is high quality then the ohms/ft is probably similar to lower quality 16AWG. Not that it really matters unless you're using a hot build in full auto cycling for extended periods of time.

    18AWG is safely rated for 16A continuous

    I do FPV too:cool:.

    Ok I will go to the store tomorrow and try to find some silicone wire in 18AWG.

    This statement is false. Battery chemistry makes no difference on if a traditional trigger trolley gets damaged.

    It's Purely Voltage. Whether is comes from Alkaline, NICD, PB, NIMH, NIZN, LIPO, LIFEPO3, LION, Nuclear, Solar, Wind....Lemons....it does not matter.

    This is how LIPO-Ready became a misnomer in this sport and people are too "hesitant" to give up that misconception.

    Oh, well something caused one of my guns to have a major meltdown where the mosfet failed and my trigger contacts were just destroyed. I had just assumed that it was because the mosfet failing created a voltage spike that destroyed the gun. But now I am wondering what really caused that horrible experience! (this was a classic army by the way, they are crap... sorry, had to rant just then:rolleyes:)

    Volts by themselves don't melt contacts.

    Two things that are the major contributor to contact damage:

    Voltage Spikes that "Zap" the metal and damages it. Then when the arc goes away its the pure AMPS.

    Here is an extreme case with 5000A, but it could happen at 50A with a smaller circuit. (Crazy Brits)



    Watch all the things they "melt" with Amps.

    Box wrenches, bolts, pokers...
