Hey man, I know you made this video 4 years ago but, it is never late to say THANK YOU. I made my own and works awesome! It been more then a year amd still going strong. Again, thank you for sharing

@pmm4177 4 года назад

Ever since I discovered flux I haven't soldered without it the past 4 years!

@southwests5508 9 лет назад

Great video! But the diode just allows current to travel only one direction to avoid feed back. So I don't think its necessary. One other thinh is you should crush the wire before u solder it then screw it to allow for more coper to attach to the surface, or just solder the wire directly. I'm assuming ur using 60/40 and coper is much more conductive that solder is. Great design. I think I'm just gonna drop the diode and maybe do silver plated. Thanks!!!

@sergiocarrero-ortiz5196 8 лет назад

How did it work so far? with out diode

@alexcurmi7412 3 года назад

Always use a diode when inductors and mosfets are linked. The inductance from the motor will kill the mosfet, I speak from experience

@jyconmatocino3892 2 года назад

hello. can this mosfet handle 170 to 210 hard spring? hope you will reply sir. 🙂

@jafarsidik180 8 лет назад

Very clear tutorial...! Is the active breaking mosfet is run? thx...

@tomdenooijer5851 9 лет назад

Hey very detailed review, helped me alot. Got a question though. Would it be possible to add a capacitor into the equation? So that whenever you lightly press the trigger, the cycle actually finishes instead of cutting out half way through , resulting in no shot.

@dedeariandy299 3 года назад

thank you for this awesome tutorial , but what happen if i use 1500 W 18A TVS diode ? it is still working properly ?? ..

@PlayTime-dk5jf 3 месяца назад

I don't know what wrong with my mosfet. I just followed the video but it's breaked my mosfet not stopping to fire.

@Recovery12Life 9 лет назад

Hello, I made this mosfet and it works very well. I did however have several issues when I installed it. the 16ga wire was to thick and I had to seriously modify my grip to get the motor to slide in and actually had to do several modifications to the rest of the gun to get the mosfet and wires to fit. I did exactly what you sad and it looked the same shape as yours but I had to grind the hole in the reciever as well as the buffer tube and the plate between. it was a but more than I had hoped for but it did work. how bad would it be to use 18ga in the future. I mean is it really going to have that much difference with motor performance?

@ExplosiveReview 9 лет назад

18 is fine if you can't fit 16. It can be a bit tricky to get in there. If you are using 18 try and use high conductance wire to minimize heating and performance loss.

@dannyboy8231995 8 лет назад

+Recovery12Life actually, 18 awg is no better than stock wire (18awg is stock wire, juts not chines stock wire) so your better bet it to use ecowire 16 awg

i use this mosfet with m140 spring 11.1v 30c baterai and m160 bigdragon motor mosfet fry just 30 second i use with full auto whats the problem ? the mosfet get to hot 6 times i try tu built it get same result mosfet fry

@mangkepwengstudio3259 Год назад

i built one, and am using 11.1v lipo battery, on my experience, i feel like with just few clicks the battery and the motor is heating fast, what could be the problem?

@oldc4838 Месяц назад

How about sir if my mosfet is IRLB4030 ? this fit?

@TriggerFpv 8 лет назад

can you elaborate as to why your using such a large ziner diode and not just a regular diode?

@rogerborg 4 года назад

It's TVS, not Zener. And he doesn't know: the diode should be across the motor terminals, not the mosfet itself.

@mr.airsoft8295 Год назад

@@rogerborgCan you elaborate on this please? I'm Interested in knowing what the difference would be.

@alphabravoas8768 7 лет назад

Where did I go wrong? I have expirience with soldering and electronics, I'm working at cellphone service, bought supplies and made few of these...some of them were faulty at the beginging, and some of them just didn't work well, as soon as I connect battery rifle start to shoot in full auto with selector in safe position. Yes, I checked diode polarity, and after this happening I used a multimeter to check it and it seems mosfets itself died...diode was ok, so as resistors. 2-3 of them worked for maybe 200 shots and then suddenly became melting hot and died... I'm out of supplies...any thoughts?

@juanderful229 4 года назад

How did it go? Did you manage to fix the design or figure out what was wrong?

@alphabravoas8768 4 года назад

@@juanderful229 no, since I couldn't figure out what was the problem. I didn't want to waste any more money on testing...

@ilhamprakoso1237 3 года назад

You need huge amps mosfet, and make sure it was original so it could hold a huge amps.

@warlax5658 9 лет назад

Hey, I'm looking for kind of a cheeper MOSFET. It seems like most have weird programming capabilities; I just want one that switches off when my lipo is running low. I'm a bit new to airsoft and I was wondering if this particular assembly fit the bill. Thanks!

@ExplosiveReview 9 лет назад

This has no low voltage cutoff but I just stop when my gun gets slugish. Haven't ruined a lipo yet.

@elioliver9554 7 лет назад

can you link me the parts I'd need to do this same thing but with a little more strength, I want to use two 7.4 2500 mAh 25c lipos wired in parallel, or are these parts enough to withstand that

@RiverFlow22 8 лет назад

Fantastic! So does a MOSFET replace the trigger trolley in an m4?

@lennyswagmaster6567 8 лет назад

Yes a mosfet like an BTC Chimera, a BTC Spectre, or an AWS raptor fet will replace the triggrr assembly but as for standard mosfets they will not

@fredrikhalasz4450 2 года назад

Got a problem after a few shots in went all auto even if the trigger is relased ?

@Recovery12Life 9 лет назад

man, I tried to make this with a mosfet and diode that I got from radio shack's parts drawers and it didn't work. I think the diode was way off it was a 6A 05 1411 and the mosfet was a IRF510. no dice. didn't work. I ordered the right parts online so I should be able to reproduce the results from the first one of these I made

@dizzytricksta8451 9 лет назад

+Recovery12Life While technically feasable, the amount of capacitance you would have to add to the circuit would be huge, and the space it would take up would be totally impractical. If you want better response get a higher C Lipo as they have the ability to dump current more quickly.

@organikness 3 года назад

What parameters must be satisfied regarding the mosfet, or do you need that exact item (IRLB3034PBF) Cheers

@gustavosouza351 6 лет назад

hello, I'm fron Brazil, installed the mosfet in my aeg but it is discharging the battery very fast, I did a test of 20 minutes firing intermittently the battery of 7.4 discharged to the point of no longer functioning aeg, has anyone ever encountered this problem?

@Recovery12Life 9 лет назад

I have some radio shack 6-amp rectifier diodes axial mounted like yours with 400amp surge for 1/2 cycles 9vpk would this be ok to use for these mosfets?

@MrSponjaBob 8 лет назад

What is the difference between using the internal diode of the transistor to the new one as used here? Moreover, I am making a simple assembly with two transistors IRF1404 to divide the intensity and remove some heating. Am I doing it right? What mounting advise me for marui EG700 engine? Thank you very much and kind regards from Spain

@hawkeye3157 8 лет назад

The internal diode of the transistor is a piece of shit. The diode used in this tutorial can actually take the voltage spikes from normal battery use. If you use two transistors, just be sure you get them in parallel with the same gate control and polarity. Sorry, I have never used that engine. Hope it helps!

@RichardAugust1993 9 лет назад

Hello! What wire type should I use when making Mosfets? Solid Wire Hook-up Wire Teflon coated mil-spec wire Silicone wire Do i realy need the mini cooler? -Richard

@ExplosiveReview 9 лет назад

Opinions differ greatly on this matter but I personally like 16 AWG stranded (not solid core) copper wire you can get at home depot or the like. Silicone wire has superior conductance but it is fragile and prone to damage. You don't need the heat sink but I like to add it as an extra layer of protection. LMK if you have any more questions.

@orcgrunt50 9 лет назад

have question regarding the mosfet as far as the gate, and the switch poles, are these designated by the wiring or does the fet say on it which is which, as you can tell not much of an electrical person so just want to make sure

@ExplosiveReview 9 лет назад

Barry Rigler Provided its a 3034 you need to build it exactly as shown. You cant switch the sides anything is on as far as I know.

@orcgrunt50 9 лет назад

thanks i got the idea now , great instructions and well layed out. at this time i dont need a fancy computerized one just something simple to protect my batteries and motor . again thanks

@asmodeuszv 4 года назад

any idea how to add precock and other stuff to it?

@orcgrunt50 9 лет назад

do have 1 more question , in regards to the wire do you recommend any preference in size. ie I am using 18 gauge on the thick wire , what size do you recommend for the thin wire , is 22 gauge good enough or is it smaller still

@ExplosiveReview 9 лет назад

I use 16 awg if I can fit it and 22 for the leads.

It does matter. The band must face the screw hole as you see in the video.

@MrBeny127 8 лет назад

😒😔I'm so pissed right now because I did EVERYTHING and got every part needed. I REWIRED THE MOSFET 4 TIMES. Still no dice. Maybe the terminal connector I'm using to screw onto the top is faulty? Maybe the resisters because I went through five of each are faulty? I mean it worked one time and I honestly don't know how it did. I pressed on the 100ohm resistor and it worked?? I have no idea. I'm just so pissed because I was so excited to built a MOSFET so I could finally use my custom built gearbox.

@dannyboy8231995 8 лет назад

+MrBeny127 Have you tried pressing the trigger contacts closer together? I thought I fucked up mine the first time too but turn out i just needed to get the trigger contacts closer

Dannyboy823 yeah. I just remade it. after I put my gearbox together after a long day of getting fired at my job, my mosfet didn't fit it. I was literally about to kill myself lmao. ill just pay stinger to do it. and for him to do a complete tech up. like shimming, aoe, etc

Why the trigger cable to the battery has to be as closer as possible?

you can really put it anywhere along the positive wire. There is a design where you connect the wire directly to the contact but I can't make it work with the 16 AWG.

Can you explain why you use a diode in your design?

@ExplosiveReview 10 лет назад

Well I'm no electrical engineer but from what I understand it acts as an overload protector for the more delicate components of the chip. Honestly you could probably use a smaller diode but this works for me and they seem to last awesome.

@BIGH1001 7 лет назад

ExplosiveReview diodes are like a one way valve. and i'm certain you could've gotten away with something not so thumpin' big. but it's probably best you used that one.

hi can you make them plug and play

I have thought about this and I don't believe so. To have plug and play it requires a much more advanced computerized circuit. I still like the direct wired version better as I believe it delivers better electrical conductivity.
