Inside the APS UAR (you know, that one that could have been a proper AUG A3)

[Im going space]

That is true. I took the middle pin out and still no movement.

[Jibbity]

I agree that it is technically not needed, but I can see the difference in flex from one side to the other with only one tab working.

Just looking inside the buttplate, anyone brave enough to cut the bits out so it can have rear wired lipos?

[Horsem4n]

i feel perfectly comfortable using thinner tri panel lipos to slip into the available space in the upper. also makes it easy to access any lipo alarms i have attached to the batteries.

[Im going space]

Yeah, considering swapping to lipos soon, the 9.6v 1500mah nimhs ive got dont seem to cycle the SHS HS motor properly.

www.component-shop.co.uk - a 7.4 2200 will cost you around £17, and the charger another £14 - Enough battery for a whole day unless you're *fruitcage* batshit nuts.

Semi auto all day, except when in anger, then 30rps

[Im going space]

Got a guarder clear rubber and a new sector chip to try out too.

[Im going space]

Right; so on sunday the polycarb half of the piston stripped.

Which makes me worry a little bit haha.

Ive thrown the piston out of my JG g36 into it for now, and swapped the funny shaped sector chip for a round one.

(Sorry for pic quality, flash killed the image and i aint reopening the GB to retake it!

[thatguy404]

Yikes, that piston is mullered!

[Im going space]

Been farting about with it in the garden this morning and its working much better now, with the new sector chip and old jg piston

[ollie_ty]

You should AoE it while youre in there. ANd also sack off that high speed motor and get the high torque instead!

[Im going space]

I have AOEd it this tine round

And im using the highspeed as it was cheap on ebay (£15 new) i use the high torque in my m16, and tbh the hispeed seems just as good on semi.

Nice informative review, but, do you think this gearbox can be a "drop in fit" into a VFC style AK? 

 

Thanks

[Horsem4n]

i dont know. i could try, but the whole thing looks more bulky than a truly standard AK gearbox. dont really see why you'd want to though.

[Isamu]

Im quite clumsy when it comes to reasemble a gearbox as the spring usually makes the whole thing blow in a thousand pieces around the room... so quick change spring gearboxes are much more comfortable to fiddle with. unfortunatly. while there are A LOT of aftermarket V2 QD spring GB, there are only two V3 gearboxes with such functionality, this, which is not sold separatly yet and the utterly expensive and unreliable ARES G36 GB.

 

Thats why I had the hope this GB could be of use to me when sold as aftermarket upgrade so I could buy it, slap an M90 spring into it and just put it into a nice AK withou spending hours of frustration and swearing trying to fit the spring in the stock GB.

 

Yes, im THAT clumsy

[Horsem4n]

ok, makes sense. i have a new AK coming in from a friend soon (RS type 56-2) and im going to try transplanting the daytonagin kit i have in my VFC AK into it. at that time i should be able to try to fit the UAR gearbox into the VFC body.

[DarkLite]

Sorry to be that guy, but it won't fit. It's designed to fit into the APS EBB AKs, which are different from the standard VFC/CYMA Ver3 gearboxes with EBB capability.

 

The major issue is that the segment that holds the AK's top cover latch is too high on the APS gearbox.

[Isamu]

Oh, thats *suitcase... will wait until any of those no name brands releases a QD spring V3 GB and not the hundredth V2...

 

Thanks for the info Darklite and the offering to try to fit it into a VFC gun, Horseman

[Jibbity]

If anyone is interested, Cyma 190rd m4 midcaps fit and feed great in the UAR. They are wide enough that they don't require any magwell shimming and it looks like the spring housing on top of the mag is short enough to fit without modifying the gun. I can't confirm the last, as I have already cut mine.

 

These I have tried, but will not feed without adding material inside the magwell:

 

KWA 120rd polymer

Core 140rd 

MAG 130rd

Green Label 75rd Emags 

[Im going space]

Ah here be the thread.

The one PMAG i tried (pts, 120/130) and the EMAG worked with the cutout and no packing. They also worked with packing. As i need a new set of mags, as much as i hate magpul i may buy 8 EMAGS. The only thing that annoys me is the price.

[Jibbity]

i made one a while back, it got turned into a bullpups thread for everything that didnt fit haha. and as fo my talk on microswitches i mean forgoing FETs totally and just wiring a switch directly into the gearbox im turning mine into a battle rifle anyways

edit: and the selectors a PITA unless you're happy using your middle finger on the trigger, then your index is free to switch it about, but mines either on safe or semi so not really an issue, and its not exactly hard to use it one handed either.

 

The point is, the standard controls may work stock, but it is much nicer all micro switched up. But, $100 was hard for me to swallow for the Chimera, I know it is not for everyone. If it weren't for the vast improvements it allows for the AUG, then I probably wouldn't have bothered for the UAR. Fortunately, with an extra trigger board (or micro switch) I can use the Chimera in both. I also feel the need to try to optimize everything, it is a sickness...  

 

How are you thinking to wire a switch directly into the gearbox? You'd have to come up with some way to get the semi cutoff to work, or just go full auto I suppose. If you can work it out with semi intact, that would be great for everyone. You'd still probably want at least a simple FET so you aren't passing all of the current through your trigger switch. It will provide a larger pool of switches to work from.

 

In any case. I will post some photos of my Chimera install in the UAR next week when I have a bit more free time. I ended up putting it inside the grip. There just isn't room in the back with all of the wiring and such.

[Im going space]

Actually didnt even consider the semi cutoff. Hmm. Is that linked to the trigger then? I meant simply replacing the contacts with a switch haha

[Im going space]

Wait wait wait, it doesnt have a standard hop? I know the unit differs ever so slightly from an AK one but inside its the same

[Jibbity]

No, It isn't compatible with standard buckings, the lips will protrude far enough to stop BBs from feeding. I suppose that means that the barrel fits deeper than normal. I had to trim down the lips of the bucking I used so that it would feed.
