| When I put CO2 on my A5, it will shoot over 300 fps, but when I put HPA on it, I cant break 240. Anyone have any ideas?? |

Have you tried adusting your VA?

| Yes, allmost all the way out. the VA makes a big difference using CO2, but on HPA, it doesnt make much difference at all. I have used 2 different HPA tanks, one of them brand new. |

Are you using a high output tank? or a low output? -------------

2300 and 2900 lbs. The tanks work fine on other guns, it is the A5 that has a problem with them. |

well I dunno what to tell you...either the tanks are low pressure..(tippmanns can only take high output) or there is something wrong inside of the A-5..heres my advice to you..take your marker apart and clean it and make sure all of the parts are there and try it again..if you still have the problem then take it toyour local shop and they will figure it out...sorry I couldnt help you out anymore but I'm completely stumped on this one.. -------------

The marker is brand new, it has less than 500 balls through it, the
shop I bought it at thought that it was my HPA tank so I bought a new
one today. It does the same thing. Both tanks are 800 lb
regulated tanks. I will take it by the local shop and see what happens tommorrow. thank you for trying. Derek |

well try cleaning your marker first before taking it to the shop like I said earlier...it would be a shame to find out that was the problem and your now being charged for the repairs.. -------------

| screw your vel.adj. all the way in then start over gradually backing it out while checking the velosity, if you have a high psi output reg. on the tank it will work just fine |

| This is a common problem with A-5's on HPA. The Problem Results from the fact that High Output HPA tanks have an Output or between 700-800psi, wheras CO2 tanks can hve higher outputs upto 1100psi thus giving you a higher velocity. The easiest way to fix this is to Get a Maddmann Spring Kit, or a RVA. Either of these will give you enough spring pressure on the valve to open it enough to give you a higher velocity. |

I had the exact same problem on my 98C. Someone else on this forum had the same problem, too. (Do a search). Neither of us were able to remedy the problem other than switching back to CO2 Please let us know if you get this figured out. Like I said, two of us have had the exact same problem and could not get it to work, although tons of others have had no problem. BTW, my HPA tankS are both Crossfire HP output tanks. They both gave the exact same problem with the exact same 260fps max. ------------- http://www.thelloydsonline.com/paintball - SPUDCRAZY http://www.oldmanmilitia.com">

. I even went as far as getting an RVA, two sets of Madmann spring kits and a Palmer Stab. No combo of all or none seemed to bring my velocity above 260fps. I cracnked on the RVA with the stiffest spring and all that happened was the spring got so tight it wouldn't recock. It did not bring my velocity up, though. Snake6 is somewhat right, but I did a test with my Palmer Stab. With CO2 I could get 280fps (desired) with the output of the Palmer at 690psi and a medium spring tension. With the exact same settings and HPA, I could barely get the marker to recock. I upped the Palmer to the max, which was 780psi and got it to shoot consistantly, but only at 260fps. I now have an ION that I use with HPA and use my Tippmann with CO2. I do use both, though, so it's great having the best of both worlds.Posted By: mbhifi

| I talked to Tippman today, they said that I needed to get the HPA up to 850-900. I think I'll just use CO2, and not worry about it. I will use HPA on my Ion. Thanks for all the help guys. Good luck |

Interesting...They didn't tell me that. I wonder how you find a tank with that kind of output. Crossfire states that theres are regulated between 700-815psi. I guess you'd have to get an adjustable reg. Oh well, thanks a billion for the info.... ------------- http://www.thelloydsonline.com/paintball - SPUDCRAZY http://www.oldmanmilitia.com">

Yeah, you would have to get a Adjustable Tank. spudcrazy, what type of RVA do you have? Alot of RVA's only move the spring out, relieving the spring pressure on the hammer. I would suggest trying the red(heavy) Maddmann Spring without the RVA, and see if that makes a difference. |

Snake6, I have a DOP RVA (see sig). I actually made a spacer to further compress the spring. And I did put in the RED Maddmann Spring w/ and w/o the RVA, to no avail. I tried every possible combo before giving up in frustration. I even broke down and brought it to the local PB shop (which I'm convinced knows very little) and even they said they didn't have a clue. However, they only came up with one or two things to try (which were the obvious). I have no faith in both of our local PB shops, even though one is the big chain store (**V's). But thanks for suggesting some ideas.
BTW, don't forget to look for us at Narnia. We'll be in a travel trailer at the camping lot. We are the Old Man Militia. We may or may not have a banner, but we should be right next to DeadByDawn. ------------- http://www.thelloydsonline.com/paintball - SPUDCRAZY http://www.oldmanmilitia.com">

Your valve spring may be a bit to strong( out of tolerance) I believe you stated in a responding post that the marker is new. Run this by Tippmann and ask for a new spring. There is allot of physics going on to blow the ball out of the barrel and they all intermingle. Why Co2 and not air, air is constant CO2 is expanding into a gas through the entire cycle and unless it is cold out is always going to build up enough pressure to get the marker to shoot well. Spudcrazy, look at your vertical adapter where it screws into the valve you might have one that the tube extends into the 90 and causes a narrow spot , you may have to drill it out. I had this problem , drilling curred it. |

| I heard somebody at my field had this problem...they were using co2 and now they are using hpa, they had to run a case of paint through it to break it in i guess.. |
