Not sure how, but taking the motor apart slightly and putting it back together fixed the issue. Hopefully this doesn't happen again XD

It'll spin, then when I take my finger off the trigger and back on, it wont spin until I turn the pinion gear into a specific place. Is this beyond repairable?

Mr hop and omega nub. I'll remember that. For now I'll be trying a s-hop and eraser nub. Maybe if next payday is good enough I'll treat myself to a new hop unit (one with the big wheel at the back so I can adjust with gloves on), Mr hop and omega nub.

That's the dream

Ok, well I'm still going to give the s hop a go, but I'll probably pick up a ml macron bucking too. I suppose the main reason for the s hop, and in fact all my upgrades, are to shut up my friend who acts like he knows everything about Airsoft, but doesn't understand why I want to swap from .2 to .28 BBS.

Lots of good reviews I suppose? I'm going for an s hop anyway as I couldn't find any silicone tubing in the right size. However, I have got some 6mm outer diameter tubing and ordered some sugru.

So, my initial question is this: Do I have to use silicone tube to make an r-hop patch? I can't get less than 1m of silicone tubing in the right size, and I haven't got a clue what my inner barrel is so I can't get one of those pre cut patches made for my barrel. However, I can get some aquarium air tubing locally. Would that do the job?

Alas, all I have to hand is a very small tub of generic gear grease. Not a lot of noise reduction (or at least not last time I lubed any gears) but seemed to do the job it's supposed to do. Onto the next step, aoe.

Cheers everyone. Gears should be shimmed ok now with shims on both sides (still very loud, but I am running 11.1s), just gotta get new motor connectors as both broke during fitting.

Do I need to have shims on both sides of my gears? My bevel gear is too close to the pinion gear if I put even a .1 shim to push it closer to the pinion. I don't have anything thinner, and I'm not sure about letting the gear run on the gearbox itself.

I shouldn't need it. I still have the original, and according to the paper test I have perfectly fine air seal between my nozzle and bucking.

Got any links to a guide? I can't find anything online and I only have a short break at work.

It's in a king arms sig 556.

The stock hop doesn't stick. I had it set perfectly at the last skirmish, then after about 3 seconds of fire the pellets were flying sky high again. Either I need a new hop or to somehow adjust this one to not move when I'm firing.

V3 gearbox with an m4 hop. I wasn't gonna go with a maxx, maybe a madbul or prowin. Anything that won't reset itself at 20+rps.

This is becoming a very expensive shopping list 😂 So, future upgrades will be: 455mm inner barrel 6.03mm Warfet Cnc hop This payday I'll be picking up a new 120 spring, a few sets of shims, some aoe shims for piston head and either a rocket 16:1 gear set, or a zci 18:1 gear set, I haven't decided yet. I was going to replace the gearbox bearings, but they should be OK right?

I have a chrono, it's just 20 miles away at a friends atm. I could pick up a precocking mosfet and stick the Nano ab in my cm16 to protect the trigger contacts.

No, haven't short stroked yet. I have some kind of compression issue somewhere, have done since I bought the gun (ex dem). Air seal is good according to tests, but I haven't been able to chrono since test so I could be firing better than I think.

Already got a gate Nano aab mosfet fitted. I'm not too bad with a soldering iron either. So, an 18:1 gearset and a 110 spring (I'm currently running a guarder sp100 at around 315 on 0.2s) with two teeth off the sector gear should do the trick with 11.1s?

It's my only working aeg. I also have a cm16 that needs a new motor. So, if I was to go with 13:1 gears, should go for a lower speed motor or switch to 7.4v batteries? I really don't want to be that guy that gives people nasty bruises from 30+ pellets hitting them at once. A little over 20rps would be fine. I need new gears regardless, and I would like good trigger response hense the 13:1 choice. Also, if my motor is going (like I said, I see sparks when it runs and that worries me) then a lower speed motor wouldn't be a problem. Sorry I keep asking all these questions, I just don't want to have to do all this again in a few weeks after breaking my gun..... Again.

So, I've just got the gearbox open, and regardless I need to replace my gears as my pinion gear on the motor has started to eat the teeth on my bevel gear (probably mu fault, probably my really bad shimming). If I was to take two teeth off the new sector gear, run 13:1 gears, set aoe and spend a day shimming the new gears, would that still be safe with 11.1 lipos and my asg 30k motor? I've seen videos that say to only short stroke the gear so you can still use the piston in another setup if needed. Also, as a side note, should a motor spark at all when run? I tested the motor out of the gun the other day and when the motor stopped there were sparks at the contact end. I also want to thank you all for your replies, if at any point it's seemed like I'm not taking anything you say in, I am, I'm just trying to also keep any unnecessary cost (such as two new lower voltage batteries) and still get decent rof and trigger response.

So, my "friend" that seems to think they know everything about airsoft doesn't know as much as they think. My gearbox has never stripped a piston per say. The first time the piston head came off and the piston got stuck, hence the stripping of the piston, this time the aoe wasn't set by the shop that did the work after the last big break (won't name names) and the rear of the piston got chewed up. So, in theory if I set the aoe properly and shim the gears properly I should be able to run 18:1 gears perfectly safe on my 11.1 lipos. Though I am very tempted to run 13:1 and maybe drop to 7.4s.

I'll be setting aoe when I put some new gears in, probably still gonna go for 13:1, but I'll also get my hands on a 7.4 and stop using the 11.1s. Short stroking etc sounds like more work than it's worth if I'm able to get 20+ rps with a lower gear ratio and 7.4 lipos.

I have not set aoe, as I only put the piston in yesterday. Im also running an asg infinity 30k motor. I'm planning on a serious updrade this friday. Full shim job, new gears (can't decide between 16:1 or 13:1 if anyone can help with that too), new 7mm bearings as mine are still stock and getting old and a set of nylon washers to set the aoe. Hopefully that'll all help fix the issue and I'll finally be able to go a whole day without stripping a piston.

Running 11.1 lipos with 19:1 gears I keep stripping pistons. Just wanted to check if this is normal, or if something is set up wrong. The three pistons that have been stripped had poly teeth, new one (not stripped yet) has a full metal rack. Am I likely to strip this one too?
