Super R/T + QEV Tutorial

I wouldn't give up my super r/t for nothing...it's one of the fastest guns on the field where i play, and everybodys got e-grips...just had to put the vortex in today bc iv'e already tore through 2 ratchets in 2 months..but I'll let ya know how the vortex turns out when i play next weekend.

Sooooooooooo you think you can hit the insanely rate of fire with the aquarium tank line??  Is that what you are driving at?  Hopefully yes when I get more CO2. And the line from home depot was to large of an inside diameter? Yes it seems so. The aquarium line is the same diameter of the line in the kit. The one that I said is a little larger than 1/8" diameter but too short(T bango to flow adjuster) I think i'm getting this right.  I just did the "q-tip" mod to mine, love it.  If you've never done it you should give it a try.  It basically stops the trigger right where the sweet spot is so that you don't need to try and hold it there.  It takes alot of fine tunning.  Also did something else.  I took a piece of a "sippy straw" and put it around one of the sear pins, which seems to have made the sweet spot bigger and easier to hit.  I don't have the insane rate of fire i would with the super rt but now that i have this set up i'm thinking of giving it another try tomorrow, since it's very easy to hit the sweet spot now.  Only thing is i'm going to have to use the .170 tubing, so we'll see how it goes.  If you are interested in those mods i mentioned i can point you in the direction as to where they are.  I'm not sure if they are listed on this forum. I'm sure I've come across those mods somewhere (sippy straw definately)but right now I want get this ironed out. Maybe in the future.   

Just remembered this.  When i was messing with the super rt mod at first i did reach a super fast rate of fire a couple of times.  It was when my CO2 was about empty, so that may have been what happened to you.  Did you notice if your cyclone was cycling at all?  If you were low on air it probably wasn't  My cyclone goes until 2 shots before the tank burps out.

I went back and looked at my post where I first hooked everything up. Although I didn't mention this then I just remembered that at first I used the hose from the kit that was too short. I placed it on the tips of the barbs to test the setup out before I used the .170" tubing. Mainly, at that point, I just wanted to see if the QEV was working. While every once in a while the tubing would leak or fall off the barbs, I think that is when I was having the good results that gave me my "false hope". You see, now that I think about it I didn't start having troubles until I used the .170" tubing. I figured as long as I got that tubing to go on the barbs tight all would be good. So compare your tubing that you got at Lowes to the tubing from the kit. It is probably a bit bigger. If you still have the tube from the kit try placing it on the tips of the barbs to test it. Good Luck.     

After I wrote my last post I tuned the same setup I had and was able to get an ungodly rate of fire for a second. I would have to pull the trigger something like 30 times before I could get the response to kick in again. It basically worked when it wanted to but when it did kick in it was insanely fast for a second.

This is using the .170" (I got at Home Depot) between T banjo and flow adjuster, and using the actual 1/8" tubing from Palmers between T banjo and the QEV. I've ruled out the adjustable feature on the QEV as a problem through trying all the different adjustments.

So later I was messing with the Protein Skimmer on our fish tank. I was adding air to the skimmer using the left over air tubing that we had from the aquariums air system. Somehow I forgot to check to see if this line would work even though you mentioned it in a past post. I compared it to the line I got at Home Depot and it was smaller in diameter but a little larger than the outside diameter of the original R/T lines. By the way, I've been using the outside diameter of the original lines as a key to tell if the inside diameter of any other line is 1/8".  The original Tippmann r/t lines fit snug into the Palmers line but in the aquarium lines it had a small gap. (I'm not sure if any of this makes sense to you)

So I put the aquarium line on and I was able to get the r/t to kick in like i had with the 1/16" setup. The "sweet spot" was easy to hit yet I wasn't able to tune in that insane rate of fire before I ran out of CO2. I will experiment more when I get my tanks filled again. So if you are using that .170" tubing it probably is too big.    

USNCV63,

Well it turns out the few quick bursts I got when I first hooked it up gave me some false hope. Three full 20 oz CO2 tanks later I have only been able to get short bursts that are slower than the 1/16" fittings. The sweet spot is hard to hold. I went to the paintball shop a couple days ago and all they had was 1/8" rigid tubing. I tried to install that but I wasn't able to get it on the barbs. Yesterday I went to Lowes and I think I found the tubing you suggested (12 cents a foot). It is the same stuff I bought at Home Depot (.170 inside diameter) I played yesterday in 21 degrees with windchill of -10 degrees. I wasn't as concerned with the r/t fittings due to the fact that my gloves barely fit in the trigger guard. I will mess around with the tubes that I have but it looks like I'm going to have to order 1/8" tubing over the internet. Good luck. Oh yeah, Palmers QEV is what I have

USNCV63,

I got my QEV today and installed everything. I stopped at Home Depot and picked up tubing that I found in the plumbing dept. It is larger than 1/8" (.170) and as I found out later not meant to handle much pressure. I put it on, to test out, and I have no leaks. I'm going to see if I can find tubing at a paintball shop tommorow. Using the left over CO2 in my tanks I dry fired and it seems everything is working great. Keep in mind no balls fired yet...but cyclone is working, QEV is venting, and from the little left over CO2 I had I was able to get a r/t rate faster than what I had before (for a few quick bursts). I need more CO2 to see if it was worth it though.

I have no idea if this would make a difference or not but on your T bango is the hole inside the valve lined up with both the hose to the MEV and the hose to the flow adjuster valve?

Thanks USNCV63,

After looking at it more, the hose from the T banjo to the fitting in the cyclone is actually the 1/8" id hose. So the hose from the T banjo to the Flow control valve is actually larger than 1/8". Are you using the kit from Tippmannparts.com?

I just received the r/t upgrade kit from tippmannparts.com and I've got a few issues with it.

 First off, the hose going from the Flow Control Valve to the T-banjo is too short. It is 2 3/4 inches long. It is a kit made for a 98 so maybe their gap is shorter. According to the site it works for the A5.

 Second, the hose from the T banjo to the future QEV has a smaller inside diameter than the other one yet larger than the 1/16". Also it comes with "orafice tube" to insert within that tube that would shrink that space to a 1/16" diameter.

Third, On the Flow Control Valve while the input where the hose is attached is 1/8", The output that goes into the grip is the same as the original fitting (1/16"). On the T banjo the input is 1/8" and on the supplied banjo fitting for the cyclone (to be replaced with the QEV) it is 1/8".

Any fittings that need to be replaced in my setup? Am I correct that I need 1/8" from the T banjo to the QEV? Thanks in advance.
