OK guys, so my g36c is brand new, and i'm using the 11.1v lipobrick on the kwa store, fully charged, and I was wondering. When I shoot the G36c on semi, beautiful accuracy, flies straight and far. But when I switch to full auto, the bbs do not go as far and are much, much less accurate, I was wondering if I could fix this before I have a war with my friends on friday. Just tell me what to do please!! :P

I have the same problem. It's most likely your battery putting out too much AMPs for the gun. I switched to an 8.4 and problem was solved. Try a non 11.1 Lipo battery, or a 11.1 Lipo with a lower C rating.

It's more that you're using an 11.1 lipo on a gun that is basically designed for a 7.4 lipo.

The reason that you do not have as much accuracy in Full auto as you do in semi, or as in the case of going down to an 8.4, is because you are essentially short stroking your gearbox as the gears spin so fast that before the piston is back in place for another shot, that sector gear is catching it mid return and you aren't getting as much compression as you would on a lower rated battery.

If you go down to a 7.4 or a 9.6 NiMH your performance should improve. If you try it and it doesn't, you should open up the gearbox and make sure nothing is stripped or warn down.

Yeah I think it's a problem with the battery, because i used it some (down to about 10.5 volts) and it started working fine.... on that note, could i just discharge it to 10.5v, or is that not good for the battery?

if you discharge it it'll mean less time to play and/or quicker time to the red line of 3v, I think it is, on a lipo. I suggest looking into 7.4v lipos they work just as well, last just as long as the 11.1s, you just won't get that insane speed you can get (in some setups at least) as you do with the 11.1s.

I've used guns with both 11.1s and 7.4s and in all honesty, I prefer the 7.4s fora couple of reasons. First and foremost, you won't be putting as much strain on your GB internals (even KWA internals will wear out unfortunately) and in your case of short stroking the piston like it is, you'll have to replace the piston and probably the sector gear after a while. a 7.4 puts as much strain on the GB as a 9.6v NiHM, with a small increase in ROF. Secondly, if you're a Milsim/Realmil player the 7.4s give you a bit closer ROF to the real steel counterparts.

ok thanks, any specific 7.4v's you would recommend? (That are guaranteed to fit in the 2gx handguard)

Jeremy and RKing, stop talking about things you don't understand at all. OP: It's possible that the gun is cycling faster than the air nozzle can seal with the hop up bucking giving you unwanted sealing issues.

That is a good possibility. I wonder if he is getting some double shots too in full auto....................

Umm, I do understand it all too well.. I've worked on guns that have striped pistons, with the same aliments as this one is having, on an 11.1v that work perfectly well on a 7.4 or 9.6 after replacing the piston. An 11.1 can cause it to short stroke by moving the sector gear in a full cycle before the piston can fully return, thus causing wear on the piston and the sector gear. Unless you modify the piston to allow the short stroking by removing a tooth or two, it is very easy to strip the piston on an 11.1.

While you say I'm wrong, you're basically saying the same exact thing I am, so let's just say that we're gonna agree on the fact that the compression/airseal isn't what it needs to be but disagree on why it's not compressing/sealing like it should.

so the verdict: get a 7.4v? any specific ones that are good?

It's not called short stroking first of all. It's called premature engagement. Secondly short stroking is when you voluntarily remove teeth to combat pre-engagement. However, this shouldn't be happening on a stock KWA unless the assembly line did a really poor job. That, or the piston is too heavy or the rails are hindering the movement. Something tells me this isn't the case because there is a horrible noise that you'll know is telling you to stop firing. I think it's possibly a weak tappet spring, or the air nozzle isn't seating properly. I concur that compression is not what it should be, but for different reasons.

If there are no other internal issues you can probably use a heavier spring to reduce or eliminate pre-engagement.

Excuse me? What exactly don't I understand? I had the same issue the poster encountered; I was running a 11.1 1600 mAH Lipo. I dropped down to a 8.4 Nimh battery and problem solved. Furthermore, I tested the gun with the same Lipo with the voltage dropped down to about 10.6, and with full auto it was able to shoot a solid stream of BBs. As a note, I was running the old 11.1 1600 mAH Kong Lipo battery from the Pro Shop.

Jeremy got the right idea.  It's not about AOE, nor the piston being too heavy.   Using a slower battery does work.  

Basically when using some 11.1v battery the timing with the Tappet plate is off and the nozzle opened a bit too long to get full compression.   if you remove the sector clip will shorten the period between opening and closing the nozzle.  Matching the faster turning rate with the motor hence it's getting full compression again.  We already did this test when using 11.1v lipo.

Another solution is adjust the angle for the tappet plate, however I'll leave that to the engineers to solve this issue.

Wow! Look at that. The same attitude you see at ASM and ASF. Self proclaimed airsoft guru.  Pathetic.................

I am curious to see if anybody has tried a LFP 9.6V and what the performance was like. I ask because due to the size of the handguard on the 2GX a standard 9.6V 1600 mah NIMH is impractical without mods (atleast for my gun). As a result I am limited to either a 7.4 or 8.4v battery.

I believe you need to remove a plastic piece to make more room.  It's nothing a dremal can't fix.  The gun does run very well with 9.6v

You said it put out too many amps, which is where I grilled you at. Amperage only affects the rate of fire when the battery cannot supply the proper current. Voltage on the other hand will.

Ah-ha! I completely forgot that KWA's came with sector chips out of the box. I personally  believe the circle design is flawd simply due to the aforementioned reasoning. It's not that there's any timing to it, it's just being delayed too long.

I, judge people by their eloquence in explaining and writing. I assumed, (which I shouldn't have) that they didn't know what they were talking about because of the use of incorrect terminology. I'd love to see your knowledge of internal workings of AEGs.

If I may make a suggestion, one could try shaving the tappet arm and the face of the tappet plate to close earlier, but I think removing the sector chip would be much easier and less time consuming.
