Move over RT! new speed KING!!

If my general knowledge of electropneumatic markers is correct, the ram operates to strike a poppet valve. The poppet valve must be struck with a certain amount of force to open and send air through the bolt to act on the paintball (or go down the barrel unhindered). The ram can still move back and forth, without enough force to activate the poppet valve if the LPR is set low enough. This knowledge is based on the workings of a bushmaster BKO. However, from what of I have seen from other stacked tube electros, they operate on a similar concept. If this is not the case with the viking, please correct me.

You are correct in one part, it works the same way. Unfortunately, if what you suggested was true, then it wouldn't make too mush sense. A gun based around this design will cycle slower when using a lower cycling pressure, and faster when using a higher one. So to make it cycle as fast as possible, turning the LPR down would make no sense at all.

It's right around 30cps.

I think J&C actually got around 34max.

Also, I don't think it's actually shooting any air,if you look at the end of the vid you can just see that it has a barrel condom on and that straps are not even moving or vibrating or anything.If I do the with a Mag or something my barrel condom pretty much goes nuts.It's hard to be sure but thats' what it looks like,so it MAY not be fully cycling and/or actually opening the valve.

On the Viking the bolt can be turned around, the marker still cycle's completely except the air isn't entering the bolt inlet. This is most likely the case here hence the barrel condom not moving.

yes

This is also why it is not as loud...

cps?

Cycles Per Second. retro valve mags were the record holders, but i think we have competition now Icom, zachs been wanting a viking for a while now, seeing one rip is just the (trying to think of something ryan didnt say) poopoo on the platter?

Not saying that it would make sense to turn down the LPR to that extent. Just trying to figure out why it doesn't sound like the marker is firing.
Also, not sure if turning down the LPR to the point where the ram is not activating the poppet valve would slow down cycle speed. Think of the LPR as a dam holding back a reservoir of fluid and the ram as a tiny stream of that fluid. If the stream doesn't need to be very big, the damn will more readily supply the fluid necessary for that stream (for the ram). On the other hand, if the stream needs to be very big (when the LPR is supplying the ram with enough pressure to activate the poppet valve) then the dam will have greater difficulty providing enough fluid for the stream - more so since the dam would have to put out an even greater volume to a river (the amount of fluid lost down the barrel). Turning down the LPR in this sense might even speed up the ram's cycling speed. Again, this is all based on conjecture, and my knowledge of fluid mechanics is not what I would like it to be, but this seems like what's going on to me. I can't think of any other reason why it sounds like only the ram is being activated and not the poppet valve.

I'm at work right now so I can't view the video.

If no one does a ROF analysis by tonight, I'll take a crack at it...

[SomebodySomeoneRTPcf]

omg what is ROF? i should know these but I just don't. Anyways what does cps do anyway? is it how fas it recharges?

[JEDI]

I don't understand all the doubt. I can understand the scientific questioning and debate, but why all the immediate doubt. The trigger is bouncing, not FA, the bolt is obviously upside down. The gun seems to be cycling. Someone posts an Emag doing the same thing, and all you here is "Wow, thats fast."

[Twon]

Very interesting, now that's something I can't do on my X-Mag. Isn't bounce illegal in tournament though?

Yes it is bounce. The guy has the debounce set on 1 on the WAS board. Here is a link to the guy talking about it:

http://www.pbreview.com/forums/showthread.php?s=&threadid=166068

I have a WASed Viking with the stock blade trigger (fat one),stock switch, and stock trigger spring and when I set debounce to 1, I can get it to bounce without any air even hooked to the gun.

I shot an excal a few weeks ago, very nice gun. I can only assume that a vik is equal in quality. I am really considering one instead of the current fold of cokie cutter electros.

2k+ shots out of a 68/4500
cheap eyes
was board
lifetime warrenty
AGD like warrenty and service
low mantience and high reliability

I think that the primary difference (aside from this being a biased forum) is that, due to design, each cycle of the mag constitutes one firing cycle, whereas one cycle from a stacked tube electro does not necessarily mean the same thing. As pointed out earlier, the ram on a stacked tube electro can cycle without actually causing the marker to fire. Because of the mag's blow forward design, each cycle includes a period where the marker actually dumps its pressurized chamber into a space where a ball would be. Of course, that doesn't necessarily mean that each ball would attain the desired velocity, but it does mean that each ball would exit the barrel.
Personally, I question so that if the marker (i.e. the vikikng) is performing in a manner in which I would like one of my markers to perform, I can possible replicate the effect.

No doubt, I've checked it and it's right around 30cps.

As far as Bouncing,probably but not absolutely.And of course that's irrelevant anyway 'cause either is an illegal setup.

As far as the bolt,obviously? I can't say that,can you? I know it's not shooting air,could be the bolt except why would you do that.Could be not fully cyclling,I can't tell from that vid.Who could?

As for a Mag,when Jack and Coke posted his FA Mag half of the posters said it was either stupid or useless or both.And many questions as to how it was done.So you have a similar response here.

Don't sweat it.It's no biggie either way.

If you guys would read the link I posted to pbreview, it would answer some of your questions:

Yes, it is bounce, not full auto. WAS boards dont have modes and they let you control the debounce. He has the debounce setting to 1 (the lowest).

Yes, the bolt is in backwards. People put the bolt in backwards when breaking in their viking. It conserves air and makes the gun a lot quiter because the passage of air normally used to propell the ball is blocked by the bolt.
