Eric, if it was black it would look just like mine. Except your inline regulator is better than mine. What I have is a simple brass ballcock with a separate plastic filter/water trap. Have you had any trouble regulating the spray pressure?

I pump the 6 gallon tank up to 160 lbs, and set the output pressure to 85 lbs, which is the max for the hose to the sprayer. Then I press the trigger on the sprayer and adjust my inline ballcock regulator to 35 Lbs while it's spraying air. When I release the trigger, it goes back to 85. When I press the trigger again, it sags to 35, but it takes a few seconds. I wonder how much paint I'll waste while I wait for it to stabilize at 35. I still have not tried it with the small harder plastic hose in place of the fabric hose. Your hose looks about like my fabric covered one.

What do you think, how does the action of yours compare to mine? I've only tried it with air so far. If I wasn't so damn gimpy I would have probably figured all this out by now without asking a bunch of questions. I might go try that narrow hose this afternoon.

EDIT: Hmm, I must have never clicked "Send..."

So I did try the narrow harder plastic hose, and I also fixed the minor leak I was working on last Saturday. I'm betting No leak is minor with an airbrush. So, now if I set the pressures as described above, when I press the trigger, it only takes +/- 2 seconds for the brush to settle from 80 to 35, and it's repeatable. It's time to try it with some paint on a test board. Whenever I do that. I'll report back and won't be too far from painting the Hyper Viper.

No not adjusting , But the paint mixing (thinning) is very important !! I use my reg. comp. witch is 20-30 gal tank Can't remember wight off , i have a water separator but have not put it in / straight from comp. 150 psi through hose 50' 1/4 " ID then to the reg. to fabric hose // I would suggest getting yourself a good regulator And have the trap at the comp. outlet (( when you do get to the point of painting get you a larger jar to mix/thin what paint you think you will need add extra ))) because tring to mix the same color again is a pain!! I guess if you measure it correctly every time you could do it in small batches . I hope that helps you will really enjoy how fast you can paint or screw up a model lol and the coats dry very Fast !! Damn!

Don't think a ballcock is good pressure regulator, I been testing with 5 to 25 lbs and pressure drop is a few lbs before it quickly gives steady airflow.
Also a two stage trigger helps, press for air and pull rearward for paint feed.
