A4 Fly Cycling Bad

[DarkCataclysm]

Hello Everyone

I purchased the A4 fly off e-bay thinking I was getting a good deal.
Came in a different box, had a few scratches, no accessories, ect. (Bad Mistake)

I ordered a new 68/4500 LP Crossfire preset tank for it. When the tank arrived I went to a paintball store with a range to test it out for the first time.

Here is my guns current setup after I played with the settings to get it to work somewhat.

Dwell is 11.
TR is 12.
LPR is 40. I can't adjust because I am still waiting on the shims I ordered from FMA to arrive. The seller of the gun must have taken some of them out.

I gassed the marker up and attempted to fire it, the bolt stuck forward and the air was hissing out of it.

Next I checked all my settings and noticed that the velocity screw was all the way in.
This makes me think that the person that used it before me had a HP Tank on the marker.
Hopefully it didn't damage any of the seals. I could not hear or feel any air leaking from the marker.

Anyway I adjusted the ram so the bolt pin was hitting the back of the ram groove so when closing the breach it clicked. I am sure that it is positioned correctly. I turned the velocity screw out so that more pressure was going to the marker.

Screw is a little less than even with mini-reg.

Then I tested the marker, it fired and it cycled. Then to make sure it was cycling properly I put the gun into demo mode. I started firing. The marker would cycle ok until I went over 15 cycles per second then it seemed to starve for air.

I played with dwell settings moving it from 11 to 14, it didn’t seem to help so I set it back to 11.

I went out of demo mode to test my velocity when shooting, the paint was high grade and a great match to the barrel, I could blow the ball through but it wouldn’t roll out.

I was getting anywhere from 280 to 310 fps, this didn’t seem right I expected 5 fps+/- or better. I am not sure why the variations are so far apart.
Dirty mini-reg possibly?

The gas consumption seems to be rather high put about 500 rounds through it and dry fired it another estimated 350 and tank dropped from 4200psi to about 1000psi is this normal??

All 500 rounds no chops btw.

I took out my angel tool kit and checked the LPR pressure it was 40 this leads me to believe that I should raise it to about 65psi to fix the cycle problems. When firing with the gauge in the LPR dropped to 20ish then popped back to 40. How fast should the lpr pressure pop back, instantly or should you see a bounce in the gauge? I knoticed a small bounce.

I ordered
1 x Angel 12 Shimms + LPR Stack Springs X (Angels)
1 x L.P LPR Service Pack (Speed/A4)
1 x Universal Mini Reg Service Kit (All Angels)
1 x Universal Seal Pack (Angels)

Already arrived =)
1 x Breech Knob
Grease and Force Oil, WDP Tool Kit

I plan on opening up the gun then cleaning it out completely and adjusting the LPR to 65.
Next I plan on using the seal pack, the mini reg service kit, and the lp service pack.

I really hope that this is going to fix the problem. This gun has been nothing but an expensive headache and I would like to see it rip some paint, since I have invested so much into it. Hopefully it will rip streams of paint to my hearts content when I get done with it.

Any suggestions on what is causing my problem?
What settings do you think I should try?

Thank you for all your help.

just got my a4 back from FMA.had it flied and mag mod done and here are the setting bob used on my gun,which absolutely mows i might add.
lpr 55
dwell 14
mini reg 250
input 450

chrono 292,294,291,292,294,293
as far as your gun goes i think the low lpr is part of your problem but the jump in the guage when firing seems like maybe your minireg needs a good servicing.i dont remember my guague jumping or at least not down to 20 anyway.hope this helps.

Well it seems like you know what your doing,

the 2004 Angel Fly Recommended settings are

dwell 12
lpr 55
imput to gun 190 or so
tr 12 or so (remember low is now a lower bounce factor and a higher number is a higher bounce factor,unlike the a4)

I bought a Gun from EBAY and all it need was a good tune up.... I still even have the gun that I use it. Run great
Ebay is such a gamble, especially when buy a gun over $500.00

One thing to remember to check is the spring stack in your lpr. Make sure that it is in the correct sequence when you put the lpr back together. Chances are that the previous owner may have put the stack in wrong...just an idea

[Talon]

Sounds like your LPR is too low as stated before, which would be causing the cycling issues since the marker needs more air than it is getting at high rates of fire. The consistancy issues can be solved by a good cleaning and servicing of both the LPR and the mini-reg. Couldn't hurt to do as you said and go through the whole thing. As far as putting it back together, follow the manual and not just the way it was when you took it apart. It's possible the spring stacks are incorrect as mentioned above.

It's always a chance buying something like an Angel off of eBay, but I've done it two or three times already and have run into similar issues. All they need is a little TLC and they'll be mowing again in no time.

Let us know how it goes. Good luck.

Bob from FMA e-mailed me this.

LPR is too low for sure. Bump it up to at least 55
and see what happens. If teh guage drops below 20
when shooting then try 60. Minreg could be dirty or
just need to be greased. It could also just be the
paint. When setting the LPR, you will need to ensure
your minireg output is at least 300psi to set the LPR
correctly.

Bob


When he said when setting the LPR you will need to ensure your minireg output is at least 300 psi he means 300+ psi from the reg to the gun?

Can the volumizer be on when setting or does it matter?

Going to try settings this weekend I will post how it worked out.

Thanks for your all your input.

[budracer1]

yes the 300 reading on minireg.350 is what manual says but if he says 300 then im sure its ok,since hes an ANGEL GOD.as far as the volumizer yes it needs to be on.set everything just like your going to play.let us know man and good luck.

how do you know what your mini reg is set at? is there some gauge or something i can buy to see what it is at?

flys and A4s have a guage on the mini reg right in front of trigger guard.

[FAIce]

A4fly they dont! but the angel tool kit have it!

[DarkCataclysm]

I believe the WDP Angel tool kit only supports pressures up to 160psi and going higher you wouldn't be able to tell output pressure and could potentially damage the gauge because it is not rated to run at pressures that high.

Here is a 3-4 faqs on making your own gauge to test mini-reg pressures that way you can set the lpr properly and test gun input pressures.

Still haven't got a chance to work on my gun yet waiting on parts.

You guys are freakin great... :bowdown: :bowdown: :bowdown: Simple and efficient.

Update:

I tuned the gun up, and put the new parts in.

I set it to the settings Bob gave me, now the gun rips!

thanks for your help everyone
