A couple of months ago I recieved a CPS 1200 in the mail that was still 1/3 to 1/2 pressurized when I got it...I imagine it had been like this for at least a week considering when I won the bidding and when I actually recieved the gun. I tested it out and it still shot reasonably well; weaker than my CPS 1000, but not that bad. I decided to do a light k-mod to return it to it's former glory.

Fastforward a couple of months, and I've finally gotten around to actually doing it...I only used 35 balloons, not much by today's standards, yet I was suprised at how powerful it was. The output jumped from 150ml/s to 250ml/s and the stream moves a lot quicker now, easily beating my CPS 1000 and everything else except my homemade. PC capacity is down to around 500ml. I think it was because of the fact that I used helium balloons; they're more expensive ($4 for 25) but the rubber seems to be thicker than regular ones. Has anyone else tried helium balloons for a k-mod? Do they actually make a difference?

Anyway, I'm quite pleased with my results, I think I might have a new favourite weapon. Roll on summer! :D

Yeah, it makes a difference, but only with those shiny pearl ones. I was k-modding my 2100, and I ran out of regular balloons, so I had to fit 20 pearl ones on. Since they were harder to get on (more resistance, didn't stretch easily) I bet they will work better than 20 regular balloons. B)

Pearlized balloons are no different than regular balloons in my experience. That's just a myth blaze started back in 2004. Pearlized balloons only add a special dye or coloring from what I know - no rubber properties are changed.

Helium balloons however I don't know about. I've never compared them, in fact I did not know that there were different balloons for helium use. They might be a better. In fact, I bet they are because helium is a much smaller molecule than most of the nitrogen and such in air. The rubber would have to be thicker and have a greater density to contain that.

As far as I know, the strength of pearlized balloons is the same as standard balloons.

Congratulations of the 12k! The CPS 1200 is still one of my favorite CPS soakers, and I find it that it fills a nice hole power-wise between the CPS 2100 and CPS 1000. Good luck on any future battles, and as usual and pics (including stream shots) would be definently appreciated!

Soak On

Well, I ended up taking off 10 balloons (I can hear the cries of protest now :P ) just to tone down the power a bit, and make pumping and the trigger easier. My original goal was to get it up to the standard of my 1000, and it has surpassed that even after I took off the extra balloons, so I'm happy with it.

So you're saying that helium balloons would be more efficient for k-modding? I've never tried anything but helium balloons so I wouldn't know the difference, but I seem to have better results with a small amount of balloons than others have. I've gotten a nice power increase, but only sacrificed about 100ml of PC capacity (with 25 balloons, not the original 35).

No, I'm only saying that I'd understand how if helium balloons resulted in a more powerful water gun. I do not know for certain if they are more powerful.

No one will have cries of protest. You know why? We've stopped putting insane amounts of balloons on pcs. Too many balloons wears out the trigger valve over time. My 21K trigger valves were ruined beyond the help of a rubber band repair. So, the current logic is that less balloons gives a sufficient powerup and helps the trigger valve function normally for longer. Basically, I probably will not put on enough balloons that a check valve freeze is even needed. Unless it is a light K over an integration, and I don't know whether the freeze will be needed as of yet in that situation. A water cannon with a smaller nozzle will accomplish the long ranges I originally wanted to pursue in modded guns, and will easily go beyond them.

XN used less balloons than are used today for a reason. ;) Well, I'm not sure whether it was to save the trigger valve from the extreme wear, but who knows?

You probably broke off the rubber seal. That happens often in high-pressure related problems. Opening the CPS 2100's firing valve can only be done with a saw, so closing it will be a pain if not impossible. Another option might be surgery with the nozzle removed, but that'd be mighty hard with a small hole to work with.

The rubber band repair actually seems to only have a 50% success rate. You know why? Becauses there are multiple problems that cause shooting while pumping, but most people don't know about them. I actually learned a lot about repairs by organizing hundreds of threads for our repair center. B)
