Serv's Spring Sales: Stampede & Vulcan

Bump

I have now made an eBay page for these springs, you can find this at: http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=130557207971&ssPageName=STRK:MESE:IT

Servulus, I think Clunk might have said this already, but do your springs run well in 15volt stampedes?

Yes, tested and it works perfectly. Actually, depends which batteries you are using? AA or something eles?

Yep I use 10 AA batteries.

I'm 90% sure it will fail with that setup due to the mAh. (i think it's the mAh)
-James

Aw dammit, could you recommend any other springs I could try?

chiiia wrote:Yep I use 10 AA batteries.

AA batteries won't work on stronger spring. They might add up to 15V, but they still cannot provide enough current to prime the stronger springs. You need Lithium-ion 14500 batteries (unprotected version) or Li-Po batteries. In fact even my four Lithium-ion 14500 unprotected batteries (add up to 16.4V) still not can't prime Servulus spring.

Added: AA batteries only can power stock spring.

The springs will work with a 12v SLA.

Gooni.

There is something worng with your stampede or your batteries because my stampede pumps the darts out with the 16.4v and Serv spring setup.

Also sealed lead acid.

I did state that I personally recommend using an SLA (sealed lead acid) battery and many others have found that some of the lithium batteries do work too. Also I have been able to get my spring to work with a set of brand new 'D' size batteries too, but they dont last for that long.

Got my spring yesterday, thanks for the quick shipping Serv.

Hey man got the other spring thanks again. These springs are beast I have in with my 12V SLA battery and tightened the seal in the plunger tube, fire the blaster on an angle 4 metres from my mates backyard fence it cleared 2 neighbours yards and landed in the third with hot glue tip streamlines.

Ok sorry for this I didn't know whether to put this in questions or here. I have one of these springs and putting it in my stampede, but I don't know what voltage is a good idea. I have been planning on 12v but I was looking and lots of people use 16v. I was just wandering what would be a good voltage. I want my gun to be powerful but also fast and light.

depends on what batteries your using.
12v SLA's are fine
and so are 16.8v of trustfire batteries

Thanks for the spring

Ok so i bought one of Serv's springs for my stampede and i just though i'd get my two cents on it. Basically it's Boss! I'm using 4x3.7v trustfire batteries over charged to 4.1 volts (thanks to clunk for giving me some advice on the battery issues) only issue i ran into was that with the extra voltage it would just full auto fire but that wasn't to hard to sort out. Havent done a rage test yet but i'll b sure to put it up later. So if your looking for a spring to mod a Stampede, i reccomend Serv's.

Thanks buddy! I love it.

Well, looks like I was right all along about my TrustFire Li-on 14500 batteries not strong enough to power Servulus's spring. After much hiatus, I finally managed to get around to experiment with my Servulus's spring today. This time I installed five of these batteries, totalling 20.4V (yes I know each battery is not fully charged up to 4.2V) and it works!!! Stampede fires hard, fast and very loud. Impressive, though I am cautious as to the high voltage more likely to cause overheating or breakage of gears. I believe now there must be manufacturing variable in Servulus's springs, and maybe mine is stronger thus requires higher voltage to work.

Good to hear that you've got it sorted. Fairly interesting about the theory on manufacturing variables. I've used about 9 of Serv's springs in various commission's and personal blaster's over the last 3 months, and not had an issue with any of them with 4 x 14500's. Even using SgNerf's 13kg spring had no issues with just the 4 batt's.

Either way, yours is running now, and that's the important bit!!

Cheers,

I also bought SgNerf's spring earlier this year, but I think it is not 13kg load, more like 9kg. You must be thinking about Longshot 13kg spring, because 13kg is too heavy for Stampede's motor. My four TrustFire batteries have no problem powering SgNerf's spring but cannot prime Servulus's spring.

Nope, it's definitely a 13kg spring. SgNerf does both 9kg and 13kg.

Oxy put me on to it. I had to hone down the spring's OD a little bit for it to fit in the plunger tube. It works fine with the AW batt's, but not with Trust/Ultrafire's. The motor's seem to handle it with no issues. I've probably put over 1000 rounds through that set-up, and no signs of wear 'n tear.

Not a phenomenal range increase, only about 5 - 10 feet over Serv's spring. Although I'm unsure if SgN still stocks them, as I haven't looked at getting any more since Serv started selling his.

Cheers,

Hmm I didn't know SgNerf also sells 13kg spring for Stampede. Despite your testing, I would be a bit worry about the 13kg load potentially breaking the teeth of those plastic gears. 9kg spring is a good load for Stampede. Servulus's spring would probably be the max I go for, in fact I would like to test it in a future Nerf war to see how long it will last.

Bump

Still have some springs left and will be putting in an order for more next week. Along with the Stampede springs i will be ordering in the Vulcan springs too.

Can I use 12v of Trustfire batteries?

Awesomenerfer823645 wrote:Can I use 12v of Trustfire batteries?

The trustfires should be fine.

How difficult is it to install the vulcan spring?

It isnt that difficult to install a vulcan spring, it just looks complicated.

Just remember how to get to each part. I've done a spring replacement. T here's alot of moving parts.

Bump.. See top page 1 for details.

Just a quick reply,

I brought 3 Stampede springs from Serv over easter weekend, threw 2 into my stampedes and one into my Night Finder Its amazing.

Stampedes are using 14.8v Lipo (2200mA) and a 11.1v Lipo (4100mA) and after 2 clips the 14.8v lipo died (hasnt been charged in a while) but those two clips were INTESNSE. I then put the spring into my "G36C" style Stampede with the 11.1v Lipo and its just amazing. I have put about 30 clips through it now and no problems at all. I get NO over runs, probably 1 or 2 miss fires in the hole clip, from a bad clip load no doubt).

Range is 23m+ (that's the length of my hallway plus dining room and rear lounge room) flat and would crank past 30m with about a 10-15degree angle using streamline darts (with hot glue filled tips). I am firing from my front hallway entrance and hitting the rear lounge room wall!!! I might take a video of it and post it up actually.

The Night Finder will do the same range FLAT as what the stamps get angled and then some. I need to find a bigger place to shoot these bullets to get a full clear range test.

Thanks Serv for some killer springs. No doubt I will get a few more of them as I build up some stamps for some other mates.

I had a PC LAN at mine (half of them are the Nerf crew also) on Monday and the G36C Stamp got a hammering from everyone, they couldnt beleive how much punch it had. I spent a fair while picking up bullets thats for sure!
