Review Overview

Value for Money


This should be your first upgrade in any AEG – not only does it safeguard your entire electrical circuit, it also boosts the performance!

Airsoft Operator is a big fan of Airlab and we have been in close contact with them since the birth of our website. After telling them about our aims regarding simplifying the complex they offered to provide us with a sample of one of their renown MOSFETS. Well what a treat! I wish just saying it’s awesome with a mention in our ‘Musings of a Noob’ series would do it enough justice – but it deserves it’s own review.

In case you don’t already know what a MOSFET does; in simple terms it reduces electrical resistance by bypassing the trigger mechanism within your AEG which actually acts as an off and on switch. Usually all the power will sit at the trigger until you pull it (completing the electrical circuit) which makes the gun fire. In order for an electrical circuit to efficiently conduct an electrical current it needs as little resistance as possible. A great deal of AEG manufacturers use thin wire and cheap connectors which naturally equate to a higher amount of resistance. We will go into more detail in another article but higher resistance will negatively affect your trigger response and fire rate.

To better explain my setup; I’m running a stock G&G CM16 Raider apart from the fact that I have had the connectors converted to Deans and I am running a high torque Lonex Titan A2 motor from Airlab, a 2600mAh 7.4V LiPo battery and an upgraded Lonex M110 spring. I ran into a few problems with using the Lonex Titan A2 motor in that it’s capable of drawing much more amperage from the battery, especially when firing in semi auto – a single shot or the first shot in automatic always puts more strain on the motor so it naturally draws more amps to compensate. I was in the middle of experimenting with better shimming / motor height adjustments and mistakes meant that I increased mechanical resistance a few times which the motor powered through like a champion but my fuse did not. Suffice to say I got tired of replacing fuses so it was the perfect time to get a MOSFET with an integrated self resetting fuse. My gun really wasn’t designed with thicker wires in mind so this is where the Dremel came in very handy – I simply widened the wire openings on the gearbox shell which ensured I didn’t cut or crush the wires and turbo charge the electrical resistance in the circuit.

I did slip up in all of this and made a silly error. For some reason I thought I wouldn’t need new motor connectors – I really hadn’t thought about it much and just assumed I could recycle my current ones. So yeah, you can’t; I bought some nice new shiny gold plated motor connectors made by Lonex from our friends at Airlab and as you can see below they worked a treat and ended up being tidier than the stock connectors.


Anyway I measured my fire rate at stock and it came in at 11.5 rounds per second. The Lonex Titan A2 motor naturally boosted this hugely on my stock spring which is why I installed a more powerful spring to counter the ridiculous rate of fire and bring the FPS on par with skirmish limitations.

But what about the MOSFET I hear you cry – well the trigger response went through the roof as did the rate of fire which is now at ~23 rounds per second. While I know that FPS and rate of fire isn’t everything I did want to push the gun to its limits before I truly enter the realm of ‘high rate of fire’. After taking it on it’s first skirmish I was even more proud of what I had created with this MOSFET as the battery life seems to have improved considerably. My G&G CM16 really is a little deceptive beast – when I let it loose on full auto it consistently got looks. I seldom give a fuck what others think about setups that have a high (or higher) rate of fire. I want and use it for two very good reasons; one being it allows me to truly lay down suppressive fire for my team mates to advance when pinned and secondly it denies those certain players of shrugging off hits a second time.

All in all I am wholeheartedly impressed with this superb piece of handmade kit – it’s taken my AEG to completely new level performance wise. All instructions were provided and Airlab were more than happy to help me through my ‘derp’ moments. I recommend this to anyone who hasn’t already made the jump to getting a MOSFET!
