How does nerf stampede work




















Ethan, You cannot fire it without batteries. Get some batteries. In the future, please read the product descriptions on the box clearly before purchasing them. Do the more powerful batteries just increase the rate of fire? If so the only way to make it more powerful is to replace the motor, spring and a couple of other parts to increase its range if the air restrictors are already out. Is that right? Heey, i removed the air restrictor and it looks exactly like your picture but my gun will not shoot the dart forward instead it shoots backwards.

Have i done anything wrong? Or do i need to complete the rest of the mods? Damien, I'm not sure what you mean by "will not shoot the dart forward instead it shoots backwards" Can you elaborate? If I use battery converters and use mh rechargeable batteries, will that help in anyway?

How can I modify the gun or increase its strength and distance of triggering. Just exchange it at the store for a new working unit, much easier. Save all the hassle. Luis, Well, the Stampede's firing system actually operates very differently from the Longshot's firing system. In the Longshot system, the bolt starts in the closed position. Users pull back the changing handle to move the bolt backwards, which in turn pushes back the plunger rod and compresses the spring, then it catches and holds the spring compressed.

The bolt is manually moved back forward to chamber a foam dart, then the trigger is pulled to release the catch and fire the shot. In the Stampede system, the bolt starts in the open position. When the trigger is pulled, the motor pushes the bolt forward but the plunger rod will still remain held back with a catch, this movement actually compresses the spring in the process until the bolt is fully forward and chambered a foam dart, then a control stalk releases the catch and the plunger rod propels forward to fire the shot.

Although both the Stampede and Longshot use similar plunger designs, they have opposite methods of operation. Perhaps you could try getting a Stampede and check it out in more detail, it uses a very interesting automated spring plunger mechanism. Luis, I know what you mean I have a stampede that im repairing for a friend he tried to mod it with out knowing what to do and screwed it up.

I've been visiting this site for quite a while now and I've read up a lot of mods for this particular gun. Not once has anyone mentioned anything about swapping out the stock motor for an upgrade with better torque with the use of higher tensioned springs. I'm hoping you know of a better motor to replace the stock motor on the stampede. SG Nerf, Thanks for the link to the forum, although I spent over 2 hours sifting through many topics, I haven't found anything that pertains to the stampede motor yet.

I just brought my first stampede, the thing has never been fired and I'm already modding it. I just got a new nerf stampede to mod. But i tested the motor when i got batteries and it Didn't Work!

I have experience with electronics so i tested it directly and i got no result. I can figure out why. Any help would be nice. If you checked everything and it still doesn't work, then it could be a faulty unit.

I guess you could get it exchanged at the store for a new working unit. I made another rookie error. I was removing the safety switches from the circuit the three magazine switches and the jam door switch and I accidentally damaged the small spring on the door that closes inside the barrel.

I can close the door with my finger and the gun will fire one shot, but if I leave the door open, the dart will only move two inches out of the magazine and get stuck in the barrel. What purpose exactly does this small door serve - it looks like some kind of air seal.

I notice your brass breech mod doesn't have this kind of setup and uses the dart as a seal instead. Anyway, what are my options for rectifying this mistake? You can see similar parts in all clip-fed bolt system blasters like Longshots, Recons, Raiders etc , they are usually called "pop-up dart tooths" in those blasters.

That door is designed to close during the chambering process when the bolt moves forward, it serves to block the foam dart and force it backwards into the moving bolt tube, thereby chambering it into the bolt to create the dart seal for firing. In such breech systems the bolt tube itself is the actual barrel itself everything after the bolt is just faux barrel, simply for show, not required at all. There is no bolt to barrel seal, so once the foam dart is fired and leaves the bolt tube, it starts losing power and speed within the faux barrel.

Without the paddle door, the foam darts will just be pushed loosely into the faux barrel and the air from the bolt will not propel them 'cos they are not even chambered with any seal at all. Its like putting a foam dart just outside the barrel of a Nerf blaster ie. Nite Finder , the air will just puff out and not even propel the foam dart. To fix the paddle door, you'll need to attach or glue back its spring. If that's not possible then you'll need to get a replacement from another Stampede.

Btw, in a brass breech system, this door is not required anymore because the breech system is converted to a proper breech to barrel seal design the bolt pushes the foam dart into the barrel and maintains the seal during firing , so the brass barrel becomes the actual barrel. I took out the AR in my Stampede and now it wont fire? Max, Most likely during the modding process you re-installed the plunger catch plate facing the wrong direction, so although the plunger is moving, the plunger rod is not catching, hence it is not being primed at all.

The solid side of the plunger catch plate should be facing the plunger not the other way around. Open the blaster up to check and re-adjust the plunger catch plate back to the correct facing, that will solve the issue. Hey SG Nerf, My friend has a problem with the stampede.

He says that when the trigger is pulled, the stampede's plunger moves back and forth normally but the dart does not fire, or even leave the clip. The batteries are fresh. Can you help?

Anonymous, If the Stampede is modded, the catch plate solid side must be facing the plunger not the other way around, a very common mistake by modders or else the plunger cannot catch and will not be primed at all hence the bolt moving to and fro but not firing anything. If it's still a stock blaster, then something inside might have been mis-aligned or broken, you'll have to open up the casing and check. With enough modding, would it be possible to move and re-wire the handle and trigger in front of the clip to make it bull-pup?

SMOGo, Yes, its possible to move the trigger anywhere on the blaster 'cos there is no need for a mechanical connection with it and the catch, the Stampede's trigger simply activates a pressure switch to on and off the circuit.

Sorry, my question is sort of tricky. I tried to make an SMG Stampede, and cut waaay too close to the plunger. The only thing that got damaged, however, was the little thing that extends past the teeth on the gear. Will this effect my blaster? If so, how can I fix it?

Milez, Okay, that part is the catch release bar, its required to release the catch to fire it. If that bar is damaged and cannot move smoothly to and fro to push up the catch, then your blaster will not be able to function properly. I guess you'll just have to work out a way to restore it back to its original working condition Thank you for your time. I noticed the motor has a 10 teeth gear on it; does it matter if the replacement motor has an 8 teeth gear?

Oscar, When the Stampede is in off mode, in theory the batteries will not be used, but you should remove them if you are not using the blaster for longer periods to prevent them from leaking over time. How many clips a battery can fire would depend on the type and quality of the batteries used. Ed, For replacement motors, i'm still testing out various types to see which fit well, but i'm not really focusing much time on it though so i can't really help you much on that aspect yet.

Replacing a motor is just a matter of removing the original motor and installing in the aftermarket motor, have to make sure all the wiring, gears and contacts are installed back in their proper positions. You should try to use gears that are the same ratios as the original gears, changes in gear ratios could affect the operation of the firing cycle.

But you're welcomed to test new gear ratios and see what happens, do post your findings though. If it is a wiring issue, replace and re-solder the wiring, same as for the pressure switches. All of this modding and attaching shields reminds me of Army of Two!

Still, I suppose that shows just how interesting Nerf guns are. Samza, Simply remove the suction tips from those foam darts and fill in the tip with the original rubber stem and abit of glue remember to attach additional soft padding to the tips for safety , then they can be loaded into N-Strike clips.

I want this so i can draw a smiley face on the wall. Sg nerf, I am getting a stampede for christmas And i was wondering if it attaches to the bandolier And how it does. Thanks in advance Nerfsnipe. I'm new to Nerf! Where do you guys get the battery converter? Paying for many batteries is what is keeping me away from this awesome gun. I need some help on which nerfs gun to get, i have the vulcan coming to me by mail but i have 60 dollars i can spend on nerf guns.

I was wondering should I spend it all on the stampede or seperate it out on other guns? I have heard about the stampedes noise from my friends and they say its very loud. I'm more of a camper in my nerf wars so i dont know if the stampede would be good for me. Is it a good deal for 60 dollars? I really like all the attachments but i dont know.

Please help! DreamCrusher, Yup, i'd recommend you to get the Stampede. It's a clip-fed motorized full auto blaster that can be shoulder aimed comfortably for quick fire and movement.

It works well in most Nerf game scenarios. Not sure how you can be a "camper" in Nerf games, even if you hide, once you start firing any Nerf blaster everyone will know where you are anyways. SG Nerf, thanks for letting me know, and what i meant by camper is i hide in a corner or behind something and basicly stay there shooting people because i usually get the crap guns SGnerf: Stampede or Air zone Punisher, if they're both the same price?

Don't waste your money on an Air Zone Punisher. Awesome gun, definatly one of my favs from Nerf, wish though they used the motor or design for this one in the REV, damn thing is loud and at least the Stampede only makes noise when it's firing not constant like the Barricade.

Until the next day when he showed his friends and it wouldn't fire. We spent about 15 clips the first day without a single jam.

Now it make the firing sound and you can see the 'pin' and spring move but the result is a dart becoming impaled and pulled back into the pins resting position. Firing again, this stuck dart just crushes the next dart in the clip. Any ideas? Hunter70, It could be due to something inside the blaster either getting mis-aligned or somehow damaged.

If you can't open it up to troubleshoot, then i'd advise to simply return it to the dept store to exchange for a new working unit. Thanks SGnerf. Its not whether you can fire the same or faster with a Raider. Its the fact that the Stampede doesn't require constant manual priming to operate. Just aim, pull the trigger and the motorized spring plunger fires all the shots automatically, so you could also use equip a second blaster in the other hand for extra firepower Can't do that with a Raider.

Also, after using it for sometime, it either fires very slowly or stops halfway through, requiring me to hit it before it can fire. I thought it was a battery problem, but then when I tested the batteries when putting them into a Vulcan, they worked perfectly. Is there anything I can do for my Stampede? I had it for about a month or so.

It won't fire in the normal position. However if you keep pointing it forward and twist it through degrees i. You can slowly twist it round but before it is the right way round it slows then stops. Foo Yang Yi, It could be due to the batteries weakening over time and usage If when used with fresh new batteries and it still exhibits this issue, then the circuit connections could be loose which create an inconsistent power supply from the battery sled.

You'll have to use a multimeter to check the circuit to see which points are loose or not allowing current to flow through properly, then replace the contacts or wiring. Mark, Check the contacts in your Stampede's battery sled, its probably loose and the batteries only have good contact when the unit is upside down.

You could try stretching the contact metal springs abit to extend their reach and help keep the batteries together more securely. And it wasn't the plunger release spring problem that you posted. I'm guessing some spring isn't catching, and only on high voltages? Do you know what is causing this. So that may be the reason that it was firing after I released the trigger?! I think that that it doesn't have enough time to retract at high voltages I have sets that fire perfectly even at 30V, while I also have sets that start to have issues at just 15V.

Your observation that the return speed of the bolt affects this issue is correct. After solving dozens of Stampede units, i've found that there are lots of different things that slow down the return speed. The plunger catch control spring positioned under the plunger is one of the reasons, a stronger one can help. Another common reason is the black return spring around the bolt is somehow slightly weaker in some units, so far many such units have been solved with a simple slight stretch of the black spring to uprate its load slightly to increase the return speed.

Yet another reason is an over-tight plunger o-ring or lack of lube, so there is added resistance internally which slows down the return speed. Also, sometimes even the casing and parts have too tight a fit due to parts manufacturing variations and need to be trimmed to reduce the resistance.

I have actually solved the issue in a few Stampedes by simply applying lube to the parts that are in contact to reduce their resistance too. I also added e-tape under the o-ring when i tested the e-tape and WD it seems to work ok.

I used a custom 12 AA battery pack i made with e-tape for the above test. When I was changing the things above I thought it had something to do with the white part that links the trigger to the pressure plate-button. After all, it only has a split second to stop the motor when the breech is open, maybe it is bouncing back?

But after the tests in the first paragraph working I don't know what to think of it- this is just an idea I think the black return spring could need to be tightened because I hear misfires if you know what i mean-no ar and sometimes no cracking sound needs padding though I just tested it and it is sucking darts up like I guessed it would do. Its not catching!!! Btw, don't use WD as lube for the plunger o-ring, that tends to damage the o-rings.

Make sure you use grease which are labeled as specifically safe for rubber o-rings. OR clip system darts K's have terrible range and accuracy and they come with the recon, and the raider. E's currently only come with the stampede and in think they are well made because the foam is much tougher and lighter than the K's.

A's come with the bandolier set and the old flip clip sets. What do you think? I've test many different batches back to back and i've found that they all fly inconsistently anyways as streamlines always do , so their performance differences seem to be inconclusive. I guess its just a batch production thing. The sight of the stampede is really inaccurate, If i use the flip up sight from Recon or Longstrike, will this help? So even if you use other types of sights, your shots are not going to land consistently on the target that you are directly aiming at other than at very close range.

For range and accuracy, you'll need to mod it to fire further so that the foam darts can travel more distance in a flat trajectory before dropping , and you'd need to custom calibrate your foam darts so that they become consistently accurate. Only then would the sight on the Stampede be usable and accurate at the targets you are aiming at. Ok,thanks If i only remove the AR's will that help?

Ok, but what if I add aftermarket spring too? Must I have voltage increase so the gun can work? Im just afraid that I might broke the gun. So although it can work, your firing speed would tend to be slower. Alternatively, you can also consider using rechargeable AA-batteries instead with AA-D shell converters , 'cos they would be more useful for use other common electronics devices Hi, i have recently got one of these from amazon and it it rubbish i have not yet been anle to fire even a single clip without it jamming, it sucks in a dart then does not fire it, it then siucks in annother one and cannot fire it because the plundger is blocked is there any way i can stop this from happenining.

Max, Looks like you got a faulty unit, just get it exchanged for a new unit that works properly. Zhi Heng, Battery converter shells can be found at most electronics parts supply shops.

Hi SG Nerf, recently my modded stampede's plunger padding flew out when I was firing. I replaced the padding and lubricated it again.

After I screwed it closed, it decided to jam every other dart. It fires the first dart, then jams on the next dart. Once I clear the jammed dart, it fires then jams. I opened it up again and checked whether I put the padding the wrong way. I did not, closed the gun, but it still refuses to fire properly. It was firing properly before I changed the padding. The only thing I did when I opened up the gun the first time other than to change the padding, was to stretch the spring to give extra range.

Is that the problem or is it something else? Try not to stretch springs, 'cos that eventually weakens them and there is a chance they get mis-shapen and cause issues during operation. I just got a stampede and im wondering what is the best batteries to use, considering that I use it a lot and need a cheap, light and probably rechargable battery. The easiest method is to use 6 x AA size Ni-Mh rechargeable batteries fitted into AA to D shell converters like the converters shown in my review.

Wow I did not know that the Stampede ECS has so many tactical rails and it comes with the most accersories. Dear sgnerf, after I have mod the Stampede, and I am using 6x1. I did change again to stock spring and still the same thing happen again In addition, if you have increased the spring load, you will also need to use power sources with higher discharge rate different from voltage so that the motor can draw enough current for higher torque, such as unprotected Li-Ion batteries.

Hi sgnerf, do you know where to buy a nerf stampede these days? I went to Metro Causeway Point branch and could not find any. Kenrick, Just check at other Metro outlets There are currently still stocks of Stampede at most places.

If you are using alkaline batteries, the different sizes just vary in mAh capacity. Their voltages are all still the same 1. Happy new year sg nerf! I have an issue only u can solve. My raider has started to jam very frequently. I have checked my darts and they are in good condition just slightly bent. Does that mean that the darts must be in perfect shape or its something with the internals. I'm very scared about messing with the inside of my gun, even if its for the better.

Pls help! Wish u an awesome year. If it still jams too often, then something inside the blaster is either mis-aligned or damaged, you'll have to open it up to check and fix It jams when u drop it down long staircases like i did :D an when it begins running out of battery. As long as you use foam darts and clips that are in good condition, the system should run smoothly.

Hi, may I know where I can still get a stampede in Singapore? Tried a few stores today but no luck. LT, They seem to be sold out at most local dept stores at the moment, even i've not spotted any at stores recently too.

I guess you'd either have to shop around at more places to find them or just wait for the stores to re-stock. Hey, thanks a lot, man. Really appreciate. The Stampede boasts a foot firing range, so the backyard or basement can be covered in soft Nerf darts in no time.

This fully automatic blaster unleashes a storm of soft Nerf darts from the extended dart clip—and it is easy to reload with the spares. Nerf Guns, or Nerf Blasters, are toy dart gun products owned by Hasbro that fire ammunition such as darts, discs, or balls constructed from foam.

It comes packaged with a Blast Shield, two eighteen dart clips, and thirty-six Elite Darts.
