20bps A5 video :O

So it that just of a stock A5 with the QEV mod and a WAS board in the E grip? Or were some other mods done to it?

Setup of the marker for the video: A-5/ WAS/ QEV/ dual Palmer Stabilizers/ titanium hammer/ JCS Gold power tube and front bolt/ RVA/ Maddman red spring/ DOP accumulator/ JCS Duel trigger/ system pressure 650 psi/ Nitro Duck 88/4500 with Center Flag 420 HPA valve. I don't have the LPK valve. My impression is that the titanium hammer doesn't make much of a difference (other than requiring a stronger spring).

The occasional skips occur only using HPA. When using CO2 with anti-siphon on the same system, there are not skips at 20 bps. The CO2 (at ~ 78°F ambient temperature) will shoot through 3 consecutively filled hopper before the tank freezes. The primary Stabilizer gets very cold, but does not freeze. The secondary Stabilizer gets slightly cool. The marker itself does not show any temperature drop.

At 20 bps, my A-5 eats ratchets like candy, and requires a second mortgage to pay for paint. I always keep extra ratchets handy. After dazzling bystanders at the chrono with 20 bps, I usually run this setup at 15 or 16 bps during play. Few people hear the difference, so they keep their heads down.

Battery life on the WAS board is significantly better than with the stock egrip board, since it can be fully switched off.

I assume you guys have seen the Rampage board vids? The guy even does a demo of an A-5 with the Q-loader.

I have hurd of a5s getting up to 26BPS, i have mine up to 22

Well I have a WAS board in my 98C ProE. I'll give that a try, go up and up before it won't feed anymore. See just how fast I can make the sucker shoot.

I have trouble with the cyclone at anything above 18 or so bps. It'll shoot the first 5-8 shots pretty as you please (because they're "preloaded" in the cyclone), but then the cyclone starts spinning too fast for the balls to effectively load, and it skips more than it shoots. People claim that a QEV on their cyclone will fix stuff like this, but I don't see how it'll help. Mine's running on a double acting ram with dual TRVs, ROF confirmed by a PACT timer - it's not that the ram/piston hoohadiddy isn't keeping up, it's that the cyclone is spinning too quickly for the balls to drop. The cyclone core just throws them around the hopper instead of letting them drop into the "chambers." I think the only way to get an A-5 to shoot consistently (key word consistently) above 18-19 or so bps is to replace the cyclone with a wicked fast force-fed loader.

EDIT - I uploaded the vid I made at 20 bps to show you what I mean - it shoots the first few shots, then starts skipping - you can see me shake it because it's skipping. Then I get a break (I was using nasty year-old paint). I've since tweaked my ram a little bit to make sure that it loads properly every time, so I don't get the chops anymore, but it still skips at high ROF.

I set mine for 18bps PSP ramping, no skipping. I'll try 20bps ramping and see the results I get. If I get continuous feeding still, or if I get skips.

The reason behind the QEV is to vent the gas from within the Cyclone piston chamber as fast as possible. Theory being that it can't leave fast enough and not allowed to fully cycle all the way back. So that after a certain speed the piston won't actually grab onto the ratchet as it hasn't moved far enough.

So with a QEV removing any excess gas from inside that chamber the spring can push the piston back faster, thus resulting in faster cyclone speed.

Right now both of these are theories. That paint doesn't feed in fast enough, or the QEV one. Unless.... yeah. An acrylic cyclone body and hopper! THAT would help pinpoint exactly which of these is the culprit, if not both.

Damn I gotta find a source for that stuff and talk to Eric about this. See if there's any chance I can sweet talk them into making... damn. Gas pressure, I need to check out the properties of the material. See if it can withstand the force being applied before even thinking of making one.

*edit*
ALSO you are using an ebolt in your A5 correct? But are you using a hammer that seals within the powertube, or the stock ram assembly?

Remember unlike the 98C port that takes gas directly from a cvx channel. The A5 is blowback specifically, and that hammer NOT sealing against the tube could be hindering your performance. Just enough that after Xbps the gas is weakened just enough to cause that trouble.

[Gatorade]

I understand the theory behind the QEV - being a long term cocker shooter does that to you. In my particular condition though (as shown on the vid) my problem isn't the ratchet not engaging (I can turn the Morlock to full auto, 20 bps, and watch it spin nice and fast-like), but the balls not falling fast enough.
I agree that an acrylic cyclone would be hot though.

[travis1581]

you can also cut the spring a couple coils. dev d has his up to 25bps with this mod and a few others

Well I was at Headrush in NY earlier today. Bought a bag of paint and did some fun work w/ my camera. Took some video and audio. However video didn't turn out as I wished. It's clean but I was shooting a net to prevent echoing from being mistaken as an actual shot. BUT it doesn't show that I was shooting paint. Which I was, all 20bps worth. Didn't misfire, didn't blend, didn't chop. Picture perfect until the battery started to go dead. Oops, forgot to change it since oh.... the Tippmann World Challenge last year! Yeah my bad.

But here are the audio spikes.


I should've shot the gun for longer periods of time, but I'll do that next time. Was only thinking of "one-one-thousand" intervals of shooting. Meh.

Soon as it gets brighter outside I'll have to re-do the video shoot then. So the video can hopefully watch the paint fly, and hit the surface like a rock or set-up plywood.

*edit*
Forgot to mention. The reason why I say longer shooting times is because of the audio clips I got. Most ended up being under a full second. This one, had I just pulled the trigger a couple more times, WOULD have had the extra couple shots to where I could show a full 20 spikes. This audio shows 19 spikes, but with a lot of extra room.

I sealed the blowback on my valve (around the stem, and out the side) - I'm not taking any gas off the side to run the cyclone; rather I run it on a 2-way air ram that is run off the same solenoid as the main ram. (there's a link to my "making of" thread in my sig - click on "ebolted A-5") The problem I'm having isn't with the cyclone not spinning fast enough. I've done some work to it since the last vid (and since I last shot it), and I'll be shooting it again this weekend. I'll test it out and see what happens

wow that was really fast... whats the A5's max rate of fire?

i don't think there is a set BPS. Tippmann will say that the cyclone is reliable up to 15 bps, after that they don't garuntee anything. but with a few mods, people have gotten theirs up higher, like the vid shown. is it reliable at even high then 20 bps? who knows

I remeber that Tippmann said it was 15bps. But on the lastest APG(April 06') pg.75 it is advertised.
Patented Cyclone™ Feed System feeds up to 17 balls per second.

Well then I guess my Cyclone is just more special than yours B-cuz I shot quite a bit more paint than what was already in the star-feed at 20bps speed. I hope to get some more paint and try 22bps and see the outcome. Well and a new 9v.

[Gatorade]

I could've been having spinning problems and not realized it - like I said, I've done a little more work to it since then, and it reliably engages the ratchet in the right place now (before, I was having trouble with it trying to double feed the cyclone, which could definitely explain the "spinning too fast for the balls to drop" problem. I'll be at NVP on Friday if you can come check it out. (either that, or let me know the next time you go to Headrush. I'm not a big fan of it, but it's convienent to meet people)


EDIT - I just performed the 101W mod on my solenoid - Aliases (Aliai?) get it from the factory - it bypasses the polarity diode and allows 25-26 cps. I made a dryfiring audiofile - can someone goldwave it for me?

I think my problems with skipping may have been due to the ram/cyclone connection not being great (as mentioned above), and not having enough paint in the hopper. I'll try it this weekend.
