Close on the heels of Kwon Yul, I also completed a unit of Flail-Armed cavalry for my Korean Army. These units are the what really attracted me to the time period. The uniforms are very different from what I normally do, and they equipment is a far cry from the usual sword and spear.
I went with a common color for the horses to lend some cohesion to the unit. I stayed with reds, blues and yellows as the primary colors for the same reason. These are essentially 5-part models (horse, rider, flail, bow, quiver) which allows them to look quite dynamic. It also makes the painting process fairly time-consuming.
