I have a bunch of airbrushes ... 3 single action suction jobs and a dual action gravity.

They all work with Ink ...... tried them with Epson refill ink ... 

But I am having trouble with water based poster paint. I was always told that the paint should be thinned similar to thin milk.

Maybe poster paint is not suitable ?

I find most of the hobby paints pigment level is to low once you thin it out for the airbrush. Ok to brush on but spraying just take 30 coats 😃

I've had good luck with those cheapo 1 dollar bottles of acrylic paints.  The colors pop well and results is a permanent stain. 

I normally thin using window cleaner as a diluting agent and bring it down to about a thick ink type of consistency. 

It does take about 3 coats to cover the larger areas but it dries fast and doesn't stink. It just smells like wet foam. Acrylics blend nicely too even when dry.
Fly like your mad at it.

Basically for it's drying agent  instead of just plain water. I used window cleaner until a guy at the hobby store told me to try alcohol and that works slick and dries quicker

Thought I'd have a look through Youtube ... very interesting about thinners. 2/3rds water, 1/3rd Iso Propanol with a shot of retarder / fluidiser in ....

I would think that the alcohol would dry too quick.I'll have to try it.

Watching Youtube vids of guys mixing thinners .... they make a point of adding 'Retarding agent' .... this slows down the drying action to allow the paint to flow and smooth out.

I will be testing IsoProp and water as I just knocked up a cheapo delta .....

WOW .... 2/3rds water ... 1/3rd Isopropanol ............. what a difference !

The mottled effect is not a problem .... in fact I quite like it ! It dried in about 30 - 45 seconds .... so giving it time to settle, but quick enough so I didn't have to wait to do second colour.

Once my IsoP runs out - I'll be at the Windex !
