Use your existing JST-connected Lipos on your Umx planes!

This is the familiar red JST-RCY female connector (male pins but female housing) wired to a standard 1S male connector (Molex Picoblade, 1.25mm pitch), like is used on the little gum-stick style single-cell lipos.

Note - make sure your battery is ONLY 1S! You'll fry your AR6400 or otherwise 1S brick if you plug in a 2 cell pack!
