Iwata Eclipse HP-CS Airbrush - Gravity Feed Dual Action, E3 Nozzle, 0.24 oz Cup Review (2026)

Who this airbrush suits

Modelers who want a single airbrush capable of both fine line work and wider coverage, rather than owning separate detail and coverage guns, are the core audience for the HP-CS. It is a 0.35mm dual action airbrush, meaning trigger pressure controls air while pulling back controls paint flow, giving more control than a single action gun once the technique is learned. The 0.24oz, roughly 7ml, gravity feed cup is well suited to smaller color batches and mixing custom shades on the fly, which fits scale model painting better than large area spraying. Someone who mainly needs to lay down big, flat base coats on large surfaces may prefer a larger cup or bottle feed setup instead.

What is under the trigger

The HP-CS uses Iwata's compression fit E3 nozzle, which the maker notes has no threads, simplifying nozzle changes and cleaning compared with threaded nozzle designs. Its high flow design lets it atomize a wider range of paint viscosities with less thinning than many detail focused airbrushes need, and the spray pattern ranges from a hairline down to roughly a 2 inch round pattern, covering both fine panel line work and broader coats without switching guns. A quick flush cutaway handle gives fast access to the needle for emptying the paint reservoir during cleaning, and the spring steel needle is built to resist breakage during normal use and cleaning.

Running it day to day

Because this is an airbrush rather than a self contained sprayer, it needs a compressor with a regulator to operate, and neither is included with the airbrush itself, which adds to the real cost of getting started. The small cup capacity means frequent refills or color changes on larger projects, though it also means less wasted paint when mixing small, precise batches of custom color. Cleaning between colors benefits from the quick flush handle and threadless nozzle, and Iwata's needle packings are built to resist solvents, which matters for anyone cycling between lacquer, enamel and acrylic paints in a single session.

How it compares with other airbrushes

Iwata's own Revolution HP-CR is a lower cost sibling gravity feed model that trades some of the Eclipse's flow range for a more accessible price point. The Eclipse HP-BCS, a siphon feed sibling with a larger 2oz bottle, suits builders who want higher paint capacity over the more compact gravity cup here. Against Paasche's Talon and Raptor models, the Eclipse holds an edge in build quality and parts availability, while Badger's 200-10 gravity feed model undercuts it on price but with a simpler single head design rather than the Eclipse's flexible nozzle setup.

Bottom line for scale modelers

With our score of 8.9 out of 10, the Eclipse HP-CS earns its reputation as a workhorse airbrush that handles most scale model painting tasks from priming through fine detail without switching tools. It is a strong pick for anyone ready to invest in a proper compressor setup and commit to learning dual action control, and Iwata's parts support means individual components like needles and nozzles can be replaced rather than requiring a new airbrush down the line. Someone on a tighter budget or just testing whether airbrushing suits them may want to start with a simpler single action model first.
