Fantastic vid Tom, It was nice to see someone got through in detail how each part works and how they work with the next part in sequence, perfect tutorial for newer techs or for people who have nit worked on a V3 box.
Thanks Mark. Once I got going I just kept talking. Cut down from 50 minutes! :)
@@AnvilAirsoftTV im not surprised, theres a lot of info to get in, very well put together 👍👍
Wow that was very informative. I went from knowing nothing about airsoft electronics to knowing exactly how a gearbox works. Thanks!
Glad it helped.
This is absolutely a perfect video for an old fart like myself (63) that’s just getting into these and wanting to do his own upgrades. I can tell there’s way more to knowing how something works vs what it takes to do significant changes but what a great start. Thanks so much for your time teaching me. Now it need trouble shooting videos. I’ll refer to hopefully other videos of yours getting super excited. Thanks and have a fantastic day
This isn’t really a tech channel. I can look after and upgrade my own gear to some extent, but I’m not competent enough to teach much beyond that.
This is EXTREMELY EASY to follow, i have learning disabilities and i can perfectly tell you what my gear box is essentially doing after watching this, thank you!
Thankyou. I glad people find this guide so useful.
Oh so you have smthing like adhd or arsperger
I have the v2, but I could still easily understand it and see how simple, yet complicated it could be. Great teaching method 👍🏼
Thanks!
This was the first time I ever "looked" inside a AEG and now I understand how they work. Great video dude! Thanks!
Glad I could help!
Thank you you are a great teacher
Great video! Very informational an pedagogic!
Great and concise explanation, thanks for making this video! I'm currently very invested in airsoft modding and this is just golden.
Glad I could help!
Great video for from you guys as always 👍👍👍 keep up the good work 😀
this was super helpful, thank you :)
Very helpful i watched a seven min vid a while back and it didnt explain much so when i heard my friend talking about stuff i didnt know i looked for a better video this was perfect thanks mate
Extremely helpful thank you so much, this will help me get into airsoft!
Damn I feel so much smarter after watching this video! Extremely educational :D Thank you very much brother!
Really good video with lots of great break downs and a really good job explaining how it works and what each parts job is.
Glad it was helpful!
Very useful and informative video. Thanks for making !
Thankyou. Is there something else you would like us to cover?
This is the best video I have seen on this thanks alot now that I know I feel comfortable going in and mucking around lol
Glad it helps
this was mega informative and to the point - really good work my dude
Glad you liked it!
Excellent. Clear and concise. Thank you.
Glad you found it useful
You did amazing explaining this.
Thanks. Never thought this video would be this popular!
amazing video. i understood everything thanks to you.
No problems
Outstanding video....so well explained and videography awesome....finally understand everything!!!! BIG THANKS!!!!
Thanks. Glad it helped
Really informative thanks. I learned a great deal.
+sarah fowles thankyou. Is there another subject you would like us to cover in a similar way?
This would help me a lot building my own gearbox! Thank you very much!
Glad we could help
Im new to airsoft and this guide is really useful, thank you very much!
Glad you found it useful
absolutely fantastic 5 stars exxxxxplanation =] thank you very much !!!
Thanks
Absolutely Brilliant Video Thankyou.
My pleasure
This was awesome !!!!!!!
Thanks
Tom, Superb video and explanation of the gearbox timing and functions. Now I know what is going on in my AEG, and so my journey into teching cautiously begins!😳 Ended up here as my newly purchased Dytac Krink SLR AK AEG is cycling twice in semi auto and firing off two BBs, in a sort of unwanted 'auto double-tap' mode!!😱
I purchased the rifle with an 11.1 volt lipo and this seems to be part of the root cause. As when I fire the rifle with one of my original 7.4 volt lipo batteries from an AR, the system only cycles a single time in semi-auto, to correctly fire a single BB. The gun is much more snappy and gives much faster full auto fire rate with the 11.1 v battery fitted. But the fact that it 'disables' semi-auto, means I will not be able to use it, unless I can somehow control/prevent the semi-auto 'double-tap' issue from occurring?
From your description of the firing system, it would seem like the extra 'kick' from the 11.1v lipo is causing the cut-off lever to not be able to release the trigger blade from the contacts in time to prevent another/second firing cycle from completing? Still not 100% sure as to why it would cycle twice though? Also not sure if I should still try to persevere to use the 11.1v lipo, and try to find a way to stop this second unwanted firing cycle from completing? Or should I steer clear of 11.1v batteries altogether for this and other reasons ? How do you know what voltage to use with what AEG, or do higher voltages require enhanced control techniques to manage the extra power oomphh and problems this seems to cause!? Perhaps another video in the making??😉
Your pretty much there. The cutoff lever doesn’t release in time to stop the already spinning motor from carrying out another cycle, it’s especially so in builds that use a weaker main spring. A good High Torque motor can help as the magnets are much stronger and stop faster. If that doesn’t work a solution is to fit a cycle detection Mosfet or use an inline Mosfet with active brake. Other than that it’s a case of serious changes to the gear ratios and potentially short stroking. I would try a different motor first and if that doesn’t work just stick to 7.4v batteries. I want to do an episode on batteries with an guest.
Thanks for taking the time to make your suggestions. The extra knowledge you provided has given me the confidence to proceed.😁😷
Thank you sir, you made my life a lot easier, nice work
Glad we could help
Be interesting to see how piston lock up happens and looks.
Good idea. I’ll do a ‘common issues’ video
Excellent video, helped so much, thanks
Glad it helped
@@AnvilAirsoftTV Tks :)
Thankss!!, very informative, it blown me how simple electronic it is, and the mechanical flow is very very mind blowing.
if it's in auto mode, does the manufacture calculate the timing for each round?? what happen if you pull off the trigger when its in the middle of loading the piston? what happen with the BB that still loading? and if I shot downwards, is the BB gonna drop the nozzle when it just loaded to the 'chamber'?
Great video, learned a lot from this
Great. Thanks for letting me know. Is there another subject or part of an airsoft Gun you would like to learn about.
Airsoft Action TV I’d be interested in process for changing inner barrel, bucking and hop unit. To upgrade a RIF from standard.
well explained tom. thanks 🙏
I’m glad you found it useful.
I do a lot of tech work and it was useful to send the link to a mate as it’s sometimes hard to explain what goes on inside a gearbox . I do watch all of your vids and like the content and the way you and gedge put things out there
top quality video.
Thanks.
Interesting video! You have good voice and clear speech)))
Thanks. I did this a long time ago now!
👏🏻 👏🏻 👏🏻 well put together. Let’s see the TM upgrade follow on video now 👍🏼 keep it up
Due for the next range trip. Audio problems.
You all prolly dont give a damn but does someone know a tool to get back into an Instagram account..?
I was stupid forgot my password. I would love any help you can give me!
@Fabian Ledger Instablaster :)
@Forrest Quinton Thanks so much for your reply. I found the site through google and Im trying it out now.
Takes a while so I will get back to you later with my results.
@Forrest Quinton WTF IT ACTUALLY WORKED :O I literally got access to my ig password after ~ 30 mins of using the site.
Had to pay 15 $ but for sure worth the money :O
Thank you so much, you really help me out !
Thanks Thompson, in the future, I am going to make UK Vz. 59. It will be unique and leggit
Excellent! I am curious of where the nozzle position should be after a full cycle using semi only. When the cut off lever trips the circuit, the motor stops but maybe the gears continue to spin until coming under load from the main spring when the sector gear starts to pick up the piston. This would mean the nozzle should be in the most rearward position after each full cycle of semi and the gearbox is at rest. Does this sound correct? I'm trying to figure out if the resting nozzle position has an impact in double feeds. Thanks.
Nicely done, good clear explanation of it. Now do a GBBR one? 😜😂👍
#StewbaccaCanHelpWithThat
This Video is great and helped out so much with understanding each part of my gun. I been trying to fix another gun that I have, it was a mosfet before and I switched it to a mini tamya-connector till I purchase a better mosfet. But when i try to shoot my gun nothing happens and the battery gets hot and the trigger contact has sparks that come out. Im a bit confused on how to fix it.
Does anyone have an idea how to fix this issue?
great video!! i have a small question. How does the nozzle create a air seal to the main barrel if it just sits over the cylinder tip ? thanks
Some have an o-ring. Others rely on an interference fit. The tip of the nozzle seals into the hop rubber.
Great explanation man straight and to the point !
Just a question, when the full cycle ends, where does the sector gears nub rest ? Does the nozzle rest in a fully retracted position after each shot ?(Assuming we're in single)
Thanks!
A complete cycle will end with all springs eased and then nozzle forward.
@@AnvilAirsoftTV In my case the cycle ends with the nozzle retracted all the way back 😬 Is that a cause for concern?
I've found the perfect video!
Wow, thanks!
So if you have a MOSFET installed instead of those metal contacts inside the trigger housing, the electrical curcuit is closed with an actual magnetic field effective transistor reducing the wear because there are no metal contacts needed to be touched, it all depends on a magnetic field is that right?
Electronic trigger units work in different ways. Some with micro switches, magnetic sensors and optical sensors. Mosfets are nothing special in general. It’s just an electronic transistor. There’s billions in the phone I’m using to type this answer on.
Wonderfull video. One suscriptor more for u. :)
Thanks for watching
Thanks you very useful knowledge, Can you make video about how AEP gun working?
I don’t have one I’m afraid
@@AnvilAirsoftTV oh ok, i just want learn more about Airsoft, whatever thanks you
Do you have an AEP gearbox explanation as detailed as this? This video is a complete education!
I don’t have an AEP sorry.
I'm having trouble with my krinkov aeg and after watching your video I think I understand what my issue is🤔
For some reason it's very particular about the bbs It will cycle smoothly. For instance I'd been running some blaster bbs through it that cycled like a dream, however I couldn't get my hands on more without ordering some online. So I bought some from my local airsoft field. Now it won't cycle any more than around 3 or 4 bbs without jamming.
After watching your video I think it could either be that the bbs are ever so slightly bigger and my rubber seal inside the piston is compromised which would stop the piston from having enough pressure to drive the bb past the rubber seal before the hop up. The gun was shooting at a consistent 270 last time I chrono though so maybe pressure isn't the issue. Or that the rubber seal before the hop up is to tight. Or the hop up maybe needs adjusting and it's making to much contact with the bb. I don't think the bbs are of bad quality everyone who I know has bought them haven't had any issues. I'm baffled.
Thank you for this video as well, I found it extremely informative and in a well presented format. That usually I would find hard to keep my attention to. You however explained everything thoroughly and kept everything to a point without reiterating anything that wasn't necessary to do so. Brilliant👍
many thanks for the kind words, BBs are all different and some guns don't like some brands. ASG BBs are pretty dimensionally accurate and are my normal recommendation.
When you open the gearbox it is common to see the gears already engaged? Like precock? stock tippman commando, Ive now put in an ssr pico mosfet same thing when i open it.
Yes it’s pretty normal in conventional gearboxes for it to be engaged at some point. Some gearboxes have a decocking feature. You really need a mosfet with a gear position sensor to totally avoid it.
Thank You for this extremely informative, yet simple to understand video. I've got two questions:
1. While shooting full auto, if You release the trigger, do the mechanisms stop mid-cycle? Or is there something that makes the mechanisms finish the last cycle?
2. What kind of motors are usually used in AEG? Is this a stepper motor?
Unless you have a cycle detection mosfet finished it will just finish mid cycle when you come off the trigger. Motors are largely very simple standard brushed RC style. There are now more and more brushless being used and there’s a couple of drone rotor motor systems being developed.
V2 having motor attached through grip seems like a worse design to me. Could you make one of these videos for the V2 gearbox? Maybe explain how to service it, what grease/oil is acceptable and best. How to shim and install components like diff motors, bearings, bushings, and o-rings. Maybe an overview of O-ring, bearing/bushing, and shim sizing/material.
I’m not really the right guy for that. Lots of other channels will have better information.
@@AnvilAirsoftTV copy mate. What are some channels you recommend?
Tom, excellent demonstration and explanation! I have a question. Both my AEG's have developed the same problem: They "fire" five or six rounds then no rounds are being shot. I pull the magazine and several balls fall out. What causes this and what will repair it? Thanks!
Responded on PM.
I have the same situation 😢
@@KrasniyByk I still have no idea why they do that. They just sit on the rifle rack gathering dust...
@@scottrobb8934 You haven't fixed that?
@@KrasniyByk I don't know how.
I know this is an old video, but i hope you can help me out...
the AK fire selector is Safe-Fullauto-semi, right? when i switch from safe to full, it shoots full auto just fine, when i go from full to semi, it shoots semi just fine, but when switching back to full, it stays in semi (with somewhat of a different noise, though). any ideas on what could be causing this?
It could be that the Selector gearing isn’t meshing quite right or that there’s a cable restricting the movement of the selector plate. I’ve had both happen.
@@AnvilAirsoftTV Thanks for the response. Amazing video, as well. Super informative.
What would you say would be the best upgraded gear box and motor for a g&g cm16 raider ?
Depends on what you want to achieve with your build. Personally I would spend the money on a more military service rifle based replica.
Hi there whats the differents between bearings and bushings and can either one can be swaped with the others. Thank you
I’ll shoot a quick video mate and put it up.
@@AnvilAirsoftTV thank you Tom
Can you choose metal gear box ratio and site for JM J12 Ak74U?
Sorry I’m not here to do your research for you.
What causes a double feed, where 2 bb's are loaded into the chamber and how do you fix it?
potentially if the tappet plate is being pulled back for too long by the sector gear you can get that issue. You might need a new tappet plate if its getting worn or you can modify the one you have.
The ICS version 2 split gearbox design is better. The gears are seperated/modular from the rest of the air drive piston assembly.
I’ve worked on a few ICS gearboxes and I don’t really like them. I don’t think anyone has really got a great solution yet. The GBLS and Systema is nearly there.
Not an airsoft player but just want to ask how the chamber fills itself with air when there is a bb blocking its front?
It’ll come down the barrel and up the BB feed pipe before the next BB is loaded. In faster cycling builds its normal to use a vented cylinder too.
after I followed all the steps you provided in the videi, my gun is shooting in continuum once I attach the battery...it shoots even if the selector is on block mode, semi, auto; I do not know what I have done in order for something like this to happen...do you have any idea what I could've done?
Sound like the trigger springs aren’t working or the trigger shuttle is stuck in the leaf springs.
@@AnvilAirsoftTV or mosfet is dead...this is what I learned from a forum...they were saying that most likely the mosfet is dead and when it is dead the gun goes on auto all the time
@@AnvilAirsoftTV no it was not stuck...everything goes smoothly on the trigger
If there is a mosfet in there, then yes it's related to that
Hey tom, I am currently designing an airsoft rifle, and I was wondering if you could provide a link to this specific gearbox, because I think that it would fill my needs best. Thanks!
Just search for an LCT gearbox version 3 and you might be able to pick one up. Depends where you live though.
What websites should I use?@@AnvilAirsoftTV
You’re going to have to do this one yourself I’m afraid and find one yourself. I don’t have the time to search google for you.
My main problem is that trigger mechanism, semi causes the trigger trolley to skip over and if i pull my trigger again it just jumps up and im effectively stuck
Sounds like you need a new trigger mechanism. May as well put a Mosfet unit in like a Titan or Perun.
@@AnvilAirsoftTV after a whole morning of troubleshooting and modifying stuff slightly, I've finally gotten it all together. Had to file a small notch into the seer and cut some plastic with a hobby knife.
I need some help. So I have a KWA km4-ris that I just spent over $100 to get fixed. Thought the shit wiring needed to be redone and restored. That wasn’t the solution to its problem. The motor is spinning no problem and the circuit is absolutely complete within the guns electric configuration. However the motor is spinning on its own without trigger pull whenever the battery is plugged in when on safety, semi, or auto. If the motor is taken out, then it will only spin on its own when put on auto, and on semi after auto until returned to safety. If put on semi, the motor will spin when the trigger is held down as if it’s full auto. And also it seems even though the motors spinning, it isn’t spinning the gears cuz it doesn’t fire even when it’s deciding to spin without trigger pull, but I feel like it’s in contact with the gears and it makes this awful noise when the battery is plugged in. I’m assuming the problem is the circuit is being completed and by looking at this video the trigger does this by the two metal pieces above making contact with one another, so why the hell is it, and how do u possibly fix that???
Sounds like you need a new trigger contact block. Or someone to go and sort out the one you have.
Anvil Airsoft TV well the weird thing now is after accidentally breaking one of the terminals that connects to the motor, and having just the bare wire touch it, it seems now it’s back to only spinning when the trigger pull. Now what my problem is, is that even though the motor is pushed in all the way, it seems like it’s not spinning the gears cuz all I hear is the motor spinning and the gun is not firing so idk what that’s about
When I shoot my LCT AK74, especially on semi, it creates this loud rattling that I think is the sound of the spring. It shoots fine and well, but this rattling is somewhat loud. Before I crack open my gearbox, I wanna know: would the spring just need readjusting, or do I need a new one? Thanks!
Doesn’t sound like a spring to me. Possibly a screw loose.
@@AnvilAirsoftTV it could be, but I'm not sure. Here's the videoth-cam.com/users/shortsKMKzNODHUnc?feature=share
That’s the anti reversal latch engaging. Nothing to worry about.
In which position should I put the gears when I am puting the gearbox together?
Put the teeth of the sector gear down towards the motor. Other than that doesn’t really matter.
@@AnvilAirsoftTV Ok, thank you
How does the mag feed the bbs in a aeg pistol
I’ve never owned one so don’t know. Sorry.
really neat, but how does the gearbox know when to stop at the right moment when it's in full auto?
It doesn’t. Which is one of the issues.
@@AnvilAirsoftTV is there a way i could solve that?
use a gear position sensing mosfet like a GATE Titan
@@AnvilAirsoftTV cool! Thabk you kindly
A little confused on the trigger. What exactly stops the trigger in semi auto. Kinda hard to see on the video?
The sector gear rotates and lifts the cut off lever which then returns the trigger trolley/shuttle to the back position. It’s covered in the video.
16:1. or 18 which one
I use 16:1 these days. Especially at UK power levels and with modern motors.
@@AnvilAirsoftTV oki
For how poorly quality airsoft components are this design looks like a wear and tear nightmare. Clever engineering but so many functions seem like they can be done without having to interact with the gears. Like the trigger disconnect.
It’s early 90s tech in this gearbox but it works for 10s if not 100s of thousands of cycles. Modern electric guns can use optical sensors to detect gear and trigger positions and control the motor with onboard ECUs. Motor tech has come a long way too though lags behind areas like drones and top RC.
Nicely done, good clear explanation of it. Now do a GBBR one? 😜😂👍
#StewbaccaCanHelpWithThat
Working on that!
