What Happened to Tippmans Propane Gun?

[nerobro]

well ive never seen a co2 tank cool off that much that quickly but i can see how it would happen.

with a brand new stab i tried to dump liquid into my pump gun and didnt get any spikes at all (and my field has a bad habbit of over filling tanks so i know there was plenty of liquid).

i dont see how a co2 tank can cool off enough to drop from 850 psi down to sub 400 psi by just shooting a pod or 2 even if u literaly dump the psi out.

I think the key words there are "tried to dump" and "pump". If you're running liquid out of the tank, you're removing a smaller volume of material. So for the tank to maintain pressure, it only need to vaporize a very small amount of liquid. You're also saying you were using a pumpgun, they use even less co2 than a semi.

If you'd like to see just how fast you can make a gun inoperable on co2, grab a 9oz tank, at room temprature. Put it into a minimag, or any mag and point the gun so tank is vertical. That will keep the CO2 in the bottle, and assure you're drawing off only gas CO2. Start fireing, fast. I'll bet you get 15 shots out before it malfuctions. With my micromag I'd get 50-60 before I'd have a block of dry ice in my 20oz.

I wonder if any of my co2 tanks are still in date... That would be a fun video to post.

I think doc has it right. A decade ago the C3 technolgy would have been a worldbeater.

i used co2 for a year and a half when i started and started again when i built my pump. i was getting +/- 2 fps weather my tank is total full or down almost empty (my gun is running at 220 psi out of the stab)

yes doc i do know all the psi-temp stuff and yes i know the chilling and filling stuff (i used to fill tanks at the field... with out a scale, totaly stupid but ididnt know any better at the time because no one there used/had/or cared about a scale)

As I've said before, the C3 was an answer to an unasked question. It has no real purpose, fills no real need, sates no real demand.

I think the question of where can gas to power a paintgun was asked. But the problem is it has been answered. 18 years ago, when the question was unanswered for a lot of people, the C3 would have sold like hotcakes.

my friend jordan has one and it sucks, propane, ha ha, propane jokes. noi it really does suck. it chops like a mother too, thats why they say it shoots 1/2 a ball per second.

if ur chopping with a pump its not the guns fault its the user

Actually with that gun its a possibility, if you fire it enough times the marker will heat the feedneck and warp the balls in the neck.

Heh, all the Smokers blew themselves up while smoking around the sucker! Stupid propane.





But seriously, I play at least once a month, or ever other - Scenarios or local woodsball stuffness, and have yet to EVER see this gun on the field yet.... ah well.

You haven't used CO2 much, have you?

Were you shooting the pump over a chronograph? Or just winging it and "seeing what'll happen"? A typical marker running unregged CO2 can easily see a 100FPS jump by going liquid, and a regulated marker that gets liquid past the reg, and then left to warm up a bit, can see more than that. The reg acts as a check valve, and so you can easily see 1,200+ psi at the valve chamber.

As for the tank cooling, a CO2 tank is only 850 PSI at 70 degrees. It's 750 psi at 60 degrees, 650 at 50 degrees, 550 at 40 degrees, and so on (very roughly, see this chart for details.)

Watch a store fill a CO2 tank. Typically they'll "bleed" it a bit (dump CO2) to cool the tank. If you've watched this, you've seen the "frost" form on the tank? That means the tank is below freezing- 32 degrees or below, or well under 500 psi. Doesn't take much bleeding to get it that cold, does it? Two or three seconds, in my experience. After ten, the tank "rattles"- the liquid CO2 inside has frozen into dry ice, twenty or thirty degrees below zero, and essentially zero pressure.

In any case, it's a moot point. The market- the players and buyers- have decided that HPA is a better propellant, and one that's basically required for any decently fast mid to high end marker.

Yes, CO2 is still a very workable and viable propellant, but HPA is better and eliminates several of CO2's definite drawbacks. As far as cost goes, while a CO2 tank is "cheaper", to get the best use, as you noted, it needs to be paired with a regulator. A Stabilizer is anywhere from $90 to $110, plus about $35 for the tank. While HPA tanks can be had for about the same price.

Doc.

He speaks the truth, I fill CO2 tanks every time I go paintballing.

What is really fun is my friend filled his 16oz CO2 tank up to probubly 15.8 oz and ran it under warm water. woo was that an interesting experience

However in my experience I've never actually seen a CO2 tank freeze or get to an inoperable pressure during normal gameplay, and combine a anti-siphon tube with a palmer stabalizer and you pretty much rule out alot of the drawbacks of CO2. If someone invented a heated palmer stab you would have almost not problums running CO2 on any gun (with the exception of an X-valved automag) with few very few problums.

Also, round here CO2 is around $0.50-1.00 per fill vs. the $10-15
HPA fill.

also just for the record most pump guns out there are designed for CO2. so really you cannot get effective results....

My friend had one an when it worked I liked it, bit big and bulky but it was still a great gun none the less.

Also if you choping you are either A: pumping to fast, 2: using crappy paint, c: being retarded.

Here's a question... "How do I get my marker to shoot flames?" I want fire to come out... and perhaps with some modifications... I could shoot paintballs that are on fire. I think that would be at least 5 minutes of pointless fun.

Fire the c3 in the dark you'll see the flames

doesent work like that, the C-3 does a good job of burning all of the propane in the chamber, at most you'll feel a little blast of heat.

That's not good enough... what's the point of a propane gun if it doesn't shoot visible flames all the time? I want something like this (note the backpack loader) to shoot paintballs:

Wagner makes the paintball version of that I believe.
