What airbrush/touch-up gun for big models?

[LDO]

What is a good choice for painting 1/8 scale cars, 1/16 tanks, 1/18 planes, etc? 

I have a regulator to get low pressure from nitrogen tanks, FWIW. 
 

Thanks

I have one of these for “big jobs”:

It’s more of a small scale spray gun than a sophisticated air “brush”, but it’s brilliant for coverage, and the single action is easy to adjust in the fly if you suddenly decide to draw lines.

I varnish 16x20" acrylic paintings in three coats with the Paasche H and #5 needle set. I shoot vertical and immediately horizontal, a quick heat set with hair dryer, repeat and repeat again. At the right distance it puts down a good 3" path of wet  paint per pass.

Or you could get an airbrush with a fan nozzle. There are a few out there. They do about the same width but in a straighter line pattern, the H has a round pattern.

A touch up gun will work but it's going to require more air volume and the tip size will be about the same as the H.

Honestly for 1/16 I use nothing special, I've even done two in lacquer with a .25 tip ! 1/8 ( depending on the model) can use a little more coverage but honestly no more than a spray can puts out. I say that as someone who decades ago shot 1/8 with spray cans and they turned out fine.

Air volume is not a problem with a 3000psi nitrogen tank.

Highly recommend the Procon PS 290 .5 with fan pattern nozzle and 15ML cup. currently $100 on amazon.  If you wanna see more about it check out spraygunner.com If you decide to get it and want a grip Iwata grip works perfect.

I just came back to say I bought one of those. I can’t wait for it to arrive. It has been years since I used an airbrush, and it was hobby enamels for military planes. I’m really looking forward to using lacquers.
