Yes, 3s works well on the "mini feigao". Feigao actually make motors similar sized to the mamba motors and they are good too. I had a 130 l can in a rc18t and ran it on 3s lipo and it hauled as.....
It also ran cooler than my 5400 mamba on 2s. Mamba motors are just too small IMO. My mini quake has way more power than it can use, worse than a 5s setup in an emaxx or 1/8 buggy. It just kind of takes off at around 45mph, and then crashes
