Questions about R/T hole

So I was tinkering around with my 98C the other day, and the little black knob that goes into the hole on the powertube where the R/T goes fell out. No worries. Now, I have 2 little questions. The first is that since this hole allows air to escape, am I losing air efficeincy? or would it just be blown out of the gun anyways even if I had that little black knob in place. Second, would Tippmann sell that little black knob seperately? Or maby somebody has an extra one kicking around that I could get......

Ok Ok. You're on to me. Here's the deal. I wanted to make my own agitated hopper, using the excess air from the gun. To do this, I took the gun apart, and discovered my Power tube was cracked. Figuring I could keep playing with it cracked, I reassembled it, aired it up and fired a few rounds. However, that little black thing shot out the side becuase the "lip" that holds it in the gun has been damaged. Therefore it is now just a cylinder, incapable of staying properly in the gun (I guess that's what you get when you buy used). All my posts have been in chronilogical order, so as something new pops up from day to day, and if I have questions, I post, looking for the answers to my questions.

Besides, so what if I've made other posts about power tubes. It helps me get a better understanding of the way Tippmann power tubes work, and I'm sure it helps others. That, and even if I didn't have problems, the answers people give me, I'll be able to help others later down the road who might be going through something similar as I am.

Now, back to the topic at hand........

I take it your little agitated hopper idea didnt pan out?

Just get a new powertube, take your valve out of your old one and put it in the new one. And be done with it. Its not smart to screw around with things that break easily.

**NEWSFLASH** "the black knob" is part of the powertube! it dosen't come off unless it gets broken off somehow, therefore this thread IS about the powertube

How do you take off the black nob without knowing its part of the powertube.

Have your ever opend the 98 before?
