Hi again, got some questions.

[Ian_Gere]

I'm just sticking with what I have with my M4, all I'll upgrade is the barrel and hop unit

I may install a MOSFET when I've got more experience of upgrading as I've only just started out but if I do, then I'll do it on 1 of my sons rifles

Does the upgraded wire make a difference Ian ??

Yes it does, quite a bit. You'll notice it in trigger response and rate of fire. Another smaller improvement is to solder the motor connections instead of the spade connectors they usually come with and, of course, swapping any Small Tamiya connectors for Deans is another small improvement.

Just make bloody sure that when you do fit a MOSFET you use heat shrink to properly cover your connections and also, if you find that it is not possible to configure your wiring so that it never gets squashed between the gearbox and receiver when reassembling, using a bit of heat shrink to add an extra thickness of insulation over the point of most squash will help to make sure that you do not compromise the insulation. These precautions are worth taking because, if you short out most MOSFETs, even for a moment, that is it for them - FUBAR. You can also help this problem by sanding/filing/dremmeling any sharp edges inside the receiver until smoothly rounded and wiping a thin layer of grease both on the interior of the receiver and the wiring.

Trust me though, it is well worth it for the fast trigger response. TBH the rate of fire increase is a bit of a pain in the arse, especially if you're using mid caps, but you can learn to get the same spread of fire as from a lower ROF by good trigger discipline firing in 3rnd bursts (or use a MOSFET which provides burst control automatically).

Thanks Ian, I have plenty of electronics experience from my rc models, what you call MOSFET, we call it an Electronic Speed Controller

Ive rewiredy rifle to front mounted battery so I can use my existing battery's but will defo rewire it all

I'm ex army so I know trigger discipline, most of the time I'm in semi auto but use 3 rnd bursts when needee

 

[Ian_Gere]

Yeah, i'm not ex military, but it's the same problem in essence with the same solution in practice - adjust the nut behind the trigger. The problem with airsoft guns though is that you can easily achieve double the ROF of real steel and when you want spread, to shoot at a running target say, firing 3rnd bursts at them only gives the same spread if you jerk the muzzle a bit - which feels counterintuitive to me and, i understand, is something you're taught not to do in the military?

 

[n1ckh]

I was always taught to lead a moving target, the point of 3 rnd bursts is so the rifle doesn't get of target with high velocity weapons

That's why amateurs with real AK's hold the trigger and hit the air

That's also why I want to add a MOSFET so I can set the ROF for 3 rnd burst, I've used a lipo and tbh, I haven't noticed much of a difference

i know there's a quick trigger mod where you adjust a grub screw to limit forward travel of the trigger but I can do that for free

 

[Ian_Gere]

Was it [a] plug'n'play MOSFET/s? Because they are fine for burst control but do not avoid the main power running through the switch, so you don't get the benefit of avoiding the high resistance the switch introduces.

Also, if the wiring is the standard 20AWG it's resistance is a major factor in the initial moments when power flows to the motor - in those 1st microseconds the motor can draw a massive amount of power (i've read that some can draw upwards of 50 Amps momentarily), if the circuit can provide it, because it has to overcome its own inertia to get moving, not just the spring load. This is where LiPo's can really shine, because their output ramps up from 0V/0A to whatever their peak output is much faster than NiMh's, so by swapping the higher resistance parts of the circuit for low res solutions you get a double whammy of improvement.

Yeah, I know what you mean about leading the target, but if your 3 rounds follow close behind each other, then if 1 misses the others may very well also, but with a slower ROF if one misses the next may hit. So if you're trying to lead a running target with high ROF 3rnd bursts, you need to jerk the muzzle of you want to get a decent spread between your BB's... which feels wrong to me when i do it

The gun im buying comes with a mosfet

 

[n1ckh]

Yes I'm looking at 1 that just plugs n plays, between the source (battery) and load (the rifle)

It sounds to me that the upgrades I'm looking at is barrel, hop unit and wiring

Tbh I'm happy with the rifle as is, I've cleaned, greased and shimmed the gear box (got my boys rifles to do)

is that the G&G top tech? If so, and I'm not trying to put you off, but there have been quite a few instances where it burns out. Also it hasn't exactly been made out as being good. If I were you I would look around, and maybe get a tech (if you don't feel safe) to upgrade the mosfet to a better one, a lot of members know good ones. That would be what I would do

still great guns btw

 

[Josh95]

To be honest I have been told every gun is bad or has flaws, except the £600 vfc guns or over priced TM's or the some how legendary "Combat machine" but their internals are actually pretty bad in comparison. Also If i upgrade anything I loose my warranty which i dont really want to do

well every gun has flaws. its a great gun, and tbh you probably won't have problems but when/ if you do start looking to upgrade that would be were I would go first
