MOSFETS MOSFETS MOSFETS!!!! WHY IS THERE SO MANT DAMN MOSFETS


So I wanna hear about them, the good, the bad, the ugly. Post up your thoughts on airsoft mosfets and explain why you liked/disliked it.

For the newer players that might not know. Mosfets are a electrically controlled firing unit that can alter firing modes on AEG's. Some offer trigger arc protection, some offer AB (active breaking). and some offer everything under the sun. (Rate of fire control, AB/Non AB. lipo protection, low battery indicator, 3-12 round burst. precocking features, and some have the espresso feature that brews you a hot cup of java on the field.

Now you might be thinking to yourself, do I need a mosfet? Why do I need one? And is it worth it? Everyone will give you a different opinion so take this with a grain of salt. there are internal and external mosfets. Internal mosfets usually take the place of your trigger switch inside the gearbox. Others are plug and play. Each manufacturer has different modes on there mosfets so do your research before purchasing.

Features like Active breaking are pretty cool but are only necessary IMO with setups that are experiencing over spin with super high speed setups. This short video on AB mosfets can explain it 100 timed better than I can so have a look

For me the most appealing feature on a mosfet(still not enough for me to get one) is the arc protection. Think of a regular trigger switch on an AEG as a piece of metal coming into contact with another piece of metal. When that happenes the circuit gets completed and power from your battery bum rushes your motor and you get a shot. The 2 pieces of metal coming into contact creates a small electrical arc, this arc over time deposits carbon on the contacts and eventually renders the switch useless. The use of high discharge batteries especially in lipo's can increase the damage done to the switch.

Mosfet arch protection reroutes the electricity energy around the mechanical switch so there is no arching at all.


now, I will be here all night if I continued this little lesson so if you are interested in learning more there are a ton of YouTube video's and reviews on mosfets that are being used around the world.

I think that some of the features that are out there for mosfets are awesome; I also think that 90% of the features are unnecessary but for others that might be different.

I only have personal experience with the Raptor internal mosfet. Which had every feature under the sun. Personally I’m not a fan. There were more hours spend working on the damn thing then I had using it on the field. And I have seen another player burn his out within one 5 hour game day. For a $100 mosfet I was not impressed. Other mosfets are externally connected and can be plugged in as easy as it is to unplug them. If something in this style of mosfet malfunctions the user can simply unplug it and be on his way. I rather replace a trigger switch every 1-3 years than have to worry about if my mosfet is going to work today or not. The beauty of the AEG electrical system is that it is caveman simple. when one post touches another post you have power, then it’s not touching there is no power..... simple... my opinion, Mosfets are just another potential piece of critical kit that can malfunction and render your AEG useless.

Me too....
Just burnt the trigger on an AK, so gonna put one in for sure. Just which one to get.

VERSION 3 for me please.

Was thinking a pico version.

Im thinking about tossing in the airsoft innovations ASCU mosfet in mine. All i really want is a crisper trigger with a better trigger response since I really like to work the trigger in semi like this http://www.youtube.com/watch?v=9hXV-Buvs1Y, hence why I have stripped so many pistons. I'm still pretty green with the whole mosfet and electronics mumbo-jumbo. But from what I've read the ASCU + a good high torque motor (Gunny suggested the Guarder Infinite High Torque motor) will give me that systema PTW style trigger I want.

I had a chance to shoot a friends AEG and I thought I was shooting a PTW. He laughed and told me it was a G&G with the Airsoft Systems mosfet, high torque motor and an Rhop. It blew me away and it was so much fun to shoot it made me almost want an M4 but now I see they have an AK version. It felt super snappy and the three round burst made me smile.

Kyle and I are using them in 6 different guns, these guns would eat/melt/pit trigger switches, most common problem, you would be in the heat of the battle and pull the trigger...just get a click, let it cool down for about 20-30 min and you could use it again for a while, also huge battery drain, the pitting would get so bad from arching that after a few use's the gun would not work at all.

mofset is the solution, high discharge lipo such as 11.1 20c and a gun that shoots up wards or 370fps will suffer switch failure sooner or later, the problem is all those amps are going right through those little slivers of tin that should operate a pen light only, they swell from the heat, then they arc, then they pit and corrode....fail.

mofset will solve the issue, just wire them in properly, support the connections so they don't pull apart and your done with 90% or your electronic issues gone! I get way better battery life, better ROF and far faster trigger response...win!

at $20-$30 and approx. 30min install time, what more can you say

I just recently got interested in adding a mosfet to my AEGs. I really like the 2 rnd burst on my KWA Kriss GBB so I thought it would be cool to be able to add burst fire to my AEGs.

After reading the good and bad reviews of different mosfets I decided to go with the BW King Kong Elite which gives you the choice of using it PnP or hardwired. The reviews were hit and miss depending on the version of the BW but I decided to give it a try anyways. The low cost of $39.99 and a decent set of programmable features including setting the burst count is what attracted me to it. Using it as a PnP mosfet out of the box will give me a 3 rnd burst with active braking. But since it can be hardwired I will be hardwiring mine to take advantage of the arch protection on the trigger. Also to change the burst count (would prob change it to 2) and still have active braking I believe it needs to be hardwired to still function.

Do I like or dislike mosfets?... I will let you know

I have a gate mosfet that utilizes the trigger contacts, but required me to de-solder some points and add a 3 wire in. Bit of a chore to get it done, because of how small the lead wire is that tells the mosfet what to do. Totally worth it, noticed instant ROF and trigger response. Best $50 upgrade I made for my gun.....other then my tightbore

Got my BW King Kong Elite installed (hardwired) on Friday night and was able to try it out in the afternoon games on Saturday. It's a pretty tight fit in my Beta Project AK with the mosfet and a 9.6v stick battery... but it fits

I programmed it with a 2 round burst which worked perfectly, I did not have any over or under burst fire round counts when using this function. Using the hardwired setup to bypass the trigger I also found the trigger response was improved slightly.

On Sunday night I was playing with the pre-cocking function for the burst fire and it appeared to work correctly. Luckily there is a small slot along the spring in my gearbox so I can see the pre-cocking in action and it seemed to improve the trigger response even more. I might try out the pre-cocking function this weekend at MRP but I'm a bit weary about the extra wear and tear on the gearbox using this function.

I like the BW King Kong Elite a lot so far and I am considering taking my G&G M4 off the market and upgrading it with a metal upper/lower receiver and adding this mosfet to it.

how much and where did you get these?

I picked it up from the manufacturer at http://www.aegwizard.com/.

It is on sale for $39.99 with Tamiya connectors (Regular price is $59.99). They also have it with Deans connectors on sale for $42.99. Shipping to Canada was $7.99 and it took just over a week to arrive.
