As you may know, I have an Echo 1 Crane Stock. When I was buying a crane stock, my 2 main contenders were the Classic Army Crane Stock and the Echo 1 Crane Stock. I decided to take the cheap road out and buy the Echo 1. Don't get me wrong, I like it, I just don't want a plastic crane stock on my metal gun. It just doesn't fit in!

So I have been planning to upgrade.

But first, let me tell you a little story about the airsoft war I had yesterday...

So I was plugging in my 4200 mah 8.4v Sub C sized battery into my crane stock, and it started smoking.  :o
Lucky me!
It was my fault, I pinched my wires, ripping the covering off of the wires inbetween my stock tube and the metal body of my gun. I should have done something, but I don't know what. ( Mini- question, what could I do to prevent this? )

My battery was fried. It's dead.


So I want to get another. I really don't know what I want, though. All I really want is a retractable full metal stock that will hold my battery, and a battery (that will last long) that will fit inside it. Also, I would like minimal wire pinching <_<

I also want a new battery and - get ready for this - I am ready to go LiPo.

I may get a battery at my local hobby shop, but if I want to go LiPo, I may want to get this online. Does anybody have a link of a LiPo that will fit in a crane stock? It doesn't matter, I don't mind staying NiMH. I also don't care too much about the weight of the stock or the battery. I actually like it!

One last thing, I don't want this to cost alot. I want to spend a max around $100, if it is a few bucks over, it doesn't matter.

Thanks for your help!

I use a crane stock on my M4 and I understand your pain. You just have to baby the battery while installing it.

But I am not aware of any Lipos that are made in the large round cell format that would fit into a crane stock. I am also not aware of any brand that makes a full metal crane stock. If you're dead set on having a metal stock, there are a few telescopic stocks (as well as folding stocks) that are metal and you can put a battery bag on the outside of them.

It doesn't have to be a large battery, I just would like it. The metal may make up for the weight.

Also, I am aware there are metal crane stocks, for instance, Classic Army makes one I was thinking about, along with King Arms.

I may also want to say that I am find with a VLTOR style stock, any stock that will hold a battery and is adjustable, and metal, of course. :)

The CA crane stock is made out of polyurethane; I know this for a fact because that is what I have. I searched the King Arms online catalogue and they are all made of plastic, including the new 2008 version which has stock pipes for AA batteries or 123a batteries.

Honestly, it doesn't matter if it's made out of metal or not. I run hard with my M4 and my plastic crane stock can take the abuse.

I don't really know of any companies that make metal stocks that house a battery.  Since the real M4 doesn't have a metal stock, pretty much all airsoft replicas have plastic stocks.  (with the exception of G&G from what I've read)  I don't see why you want a metal one so bad?  Do you plan on throwing your gun on the ground?

If you were to get a metal crane stock it would add a lot of weight to your gun, your gun along with a battery will be very back heavy :lol:

I have never seen metal crane stocks either....

OK, I guess there are no metal crane stocks. You guys really beat me into the ground about that one!

But I still would like to upgrade my cheap plastic Echo 1 crane stock. It may not be metal, but anything over a cheap plastic would be nice.

For instance, You all know the feel of plastic, right? It just doesn't seem real. However, if you feel the stock the KM-4s came with, you would notice the difference. It is a big difference, you will notice.

And I absolutely HATE the system on the back of my crane stock. The opening is WAY too small! I have no room to disconnect my battery while not in use, and it could have been my reason why my battery started smoking.

And it may look the same, but I want it to feel the same.

Also, I LOVE the heavy weight on the back. I feel like I can turn corners so much faster!

Hey urban_epidemic,

Is the Classic Army crane stock hard to connect/ disconnect the battery through the back?

And anyone else, have you guys seen ANY sized li-po battery that will fit a crane stock?

Lipos won't fit. But the Li-mn most likely will.

well its just as difficult to install a battery as in any other crane stock. You just got to be really really careful otherwise you'll rip the wires off their leds (I've done it twice to one battery already) but they can be soldered back on.

And yeah, I have not see any Lipos made in the round large C-cell format.

So you have that 1" by 1" hole to plug your battery in?

And they don't have to be a large SC cell, because I was planning to upgrade my stock, I may be changing the size of my battery.

@ Allizard

Do you have any links on Li-mns for a crane stock? Are they as good as lipos?

And I did find a LiPo for a crane stock, by the way-
http://www.checksixa...od=HP-11.1-2200

The cells look flat though, and they don't say the size.

Those battery packs are same size as the Firefox on eBay.  But the wiring look pretty crappy.

We have talked with Evike yesterday about the Li-mn and they will try those on their crane stock.  
As for performance they are just as good if not better than li-po.  I'm using them already and I really like them.

Cool! Could you answer these questions?

Do they need a special charger, or could I use my Universal Charger I got off shorty?

And could they explode? (I know they probably won't, but I would like to know)

Can they use a standard tamya?

Lastly, you said Evike will be putting these in a crane stock. Do you know what size batteries they will be? Or will they be shaped like LiPos cells?


I have also been looking into the G&P crane stock. Do you have to cut the metal body to install it?

Thanks a lot for your help!

You have to use charger that is specific for lipo.


And could they explode? (I know they probably won't, but I would like to know)

Silly question.  Any battery will explode if you mistreated or abuse it.   Battery don't explode under normal use.  That said, Li-mn have a metal casing and it's more durable on impact.


Can they use a standard tamya?
They are using Tamiya.

Lastly, you said Evike will be putting these in a crane stock. Do you know what size batteries they will be? Or will they be shaped like LiPos cells?

Didn't I show I picture of the li-mn that I'm using?! They are cylindrical shape.

That I'm not sure at the moment.  I don't like the shape of crane stock myself, therefore I don't use it.

Thanks a lot for your help!

Remember my second problem? Where my wires are pinching?

Well I have a solution, but I want you guy's approval on it.

You know that hole you put the screw in the back of the gearbox so the stock tube goes on? I was thinking about dremeling that hole to make it bigger, so my wires could go through, without the pinching.

Take a look here-

See what I mean? will that be OK?

I wouldn't suggest it.  That screw not only secure the stock tube but also secures the rear of the mechbox. Route your wire from the bottom opening and reroute into the stock tube. ;)
