Hi
your ANEST IWATA LPH-80 is a bit of a overkill in my opinion.
I'm using a Custom Colors 130 with a 0.3mm needle and a fixed 7ml cup (It looks a bit like your Iwata eclipse HR-CS), and I just did a 1:10 RC Sd.Kfz.222-110 panzer (48cm long), also had a Custom Colors 134 which is basically is the same as the 130 but with detachable cup/glass but cannot locate at the moment

the same for my Badger 150. (I need to clean up my workshop too many things is missing right now).
I'm using Vallejo acrylics and use a mixture of 50/50 airbrush thinner and flow improver as thinner, 4-5 times the amount of paint works for me. With the primers 1-3 to 1 primer. With Air 1-2 to 1 paint.
Bought some small PE bottles of Ali express so I can mix larger portions of paint and just top up the cup during the paint session. I always put a 4-5mm ball in the paint bottles before shaking them.
For the details I have a Custom Colours 201 without cup and 0.2mm needle, works great for small items and details.
I seal the paint with Vallejo acrylic on a spray can.
BTW Custom Colors is a rebranded Chinese airbrush. You can see pictures of them here, sorry it's in Danish
