>>6909908as far as i know , those small compressors barely have any power , they are more suited to do really fine stuff like makeup on large areas rather than moving heavier pigments like paints for modelling , i do have a cheap compressor of the next tier than the one on your pic ( if i recall your kit should be around 50$ , i go the next tier , the 80-90 one with the bigger compressor but withouth reservoir) mine works fine as long as i don´t paint for more than 15 minutes straight , that burns the engine so i just plan ahead how many parts i´m going to work on a sittin , and i´m usually done withn 10 minutes.
the cheap compressors lack any pressure setting so you have to swicht needles if you use heavier pigments ( i use the bigger for enamels, otherwise the aibrush clogs within 5 secs)
