Iwata Eclipse

id go with the CS. yeah, the cup is on the large but side if you happen to shake it by accident it won't spill everywhere. 

I agree with the others. You don't have to put much in it even though it has a larger cup.

That is the nice thing about gravity-feed airbrushes.

I would also say the HP-CS as I would certainly find the cup on the HP-BS a bit on the restrictive side.

I have been using a single action airbrush and want to get a double action airbrush that I could use for detailing also. I was thinking about the Iwata Eclipse and was wondering if it is better to get the bigger cup or smaller cup? This will be my only airbrush I will be using for my airplane and car builds.

I have the Eclipse HP-CS as my main modeling airbrush. Its cup size is better suited for modeling than the small HP-BS cup. Just my personal opinion.

Well I'm use to the Aztek brand  brushes and got a small and large cup so all I got to do is swap out the big cup  to small cup for the smaller paint jobs don't waist as much paint that way

 But for you I would go for the large cup and after a while you will get to know how much paint and thinner you need for it unless of course you can remove them like I can with the Aztek then it would not matter.

well since you do cars they require more paint so i would go with the big cup so you dont have to constantly add more paint other than that there identical.

a ( siphon feed model ) is even better cause you can use the large paint jars, which is usefull for clear coating when you dont want to stop halfway through if you run out of paint!
