That is the Paasche model AB and it is very difficult to use from what I am told. Leave it to the illustration artists as us modelers don’t need it. [:D]

I got the Aztek in yesterday.
first impression:… it looks cheap, lol. I guess I am just used to the all metal of the Paasches that I have. The Aztek is all plastic.
I sprayed around with it a little bit. I am really impressed with how it performs. The double action lever has ALOT of play in it. I mean, it has twice the pull back of my VL. It is really nice and lets you explore even more control with line thickness. It comes with 6 nozzles, and is a really neat idea. Each nozzle contains the needle and everything for each kind of paint. So if you want to do a .30 thickness line, you slap on the white nozzle and get down.
To clean up, you just take the nozzle off of the brush and soak it in water or thinner or whatever. You can also rinse the front end of the brush if you want, and thats it. VERY easy clean up. I think I will really like this.
I’ve enjoyed my Aztek for years and I use it for other applications.
So I have to ask, how did Model Expo treat you?
Squadron did me right on my order.

Model Expo did me right. Good group. They are also only like 100 miles from me, so UPS is only 2 days which is nice.
Great Models is a joke. I will never buy from them again.
Squadron did me right also. All 3 times. I just got in my 16th package today… I have had a bit of experience, 
Well, being an engineer I am fascinated by little moving thingies!
Glad to hear it. I live in East Central Florida so Model Expo is pretty convenient.
I run a window of 20-30 psi through the Aztek, depending on the paint mix I’m trying to push through it. Inks and dyes only take about 15 psi. Its a constant fiddeling to adjust for the best performance. I rigged an inline valve so I don’t have to go back to the compressor to adjust. (I use my larger shop compressor).
Worse case you can pull the tips apart for thorough cleaning. But not for the faint of heart. (I’m used to pulling technical pens apart and cleaning them so the Aztek tips are sort of the same). Pick up a bottle of acrylic thinner to use as a flush between colors and a squeeze bottle of airbrush cleaner. Once your in the habit of cleaning it it will become second nature and you won’t lose much time. THe best advice I can give y ou is get some cardstock and practice playing with the airbrush. Find a cheap paint or watercolor to run through it and practice shooting distances, settings, trigger control etc. Its easier and cheaper to that than to do a spatter job on your f-16.

The Pollyscale acrylics can be thinned and cleaned
up with water. Sodium free distilled water works great
and it’s cheap. Great for decals too. Rubbing alcohol
can be used with pollyscale also.
Straining Polly scale will keep lumps of paint from
clogging the airbrush or ruining your finish.
Hope this helps,
