The first spray equipment I bought many years ago was a Paache H type airbrush. I used it to spray dope finishes on CL models. It will spray a pattern about the size of a nickle with model dope. Still have it some 35 or 40 years later and still use it but mostly for model RR projects and plastic display models.

The second airbrush I got was a Paache VL. It will spray dope in a pattern about the size of a quarter. It will also spray thicker liquids than the H type but as someone else said, cleaning or changing colors is a lot more trouble because of all the extra parts. If you don't keep your airbrushes scrupulously clean you will regret it in very short order.

The next gun was a Badger 400-2 detail/touch up gun. It will spray a pattern about 2-1/2 to 3 inches in dia. I love this thing. It was cheap and isn't as fussy about what you put through it. The thing will spray polyurethane varnish straight from the can with out thinning.

The next one was a DeVilbiss JGA. This is a full size proffessional grade automotive gun. It is, as you would expect, excellent but wan't cheap. I think I gave around $200 for it.

The last one was a DeVilbiss touch up/detail gun. Think I gave around $150 for this one. Again, it is professional grade and I have zero complaints.

I have a 25 year old 2 cylinder, 20 gal. tank, 9 CFPM at 40 PSI Sears compressor that rusn on 220 volts. Just put a new motor on it a year or so ago. It's plenty for spray painting.

My opinion? I think you would be better off with an inexpensive detail gun to start off with given that you say you want to spray .60 size planes. Btu then again, I am just a hobbyist and I'm sure there are pro painters on this board who can tell you more than I can.
