For those of you who want to build an Umma85 from the ground up and source your own parts, this is where you start. This is the "upgraded" Beta85x 4S 4K frame kit that includes the carbon brace, and has some changes to the plastic. Grab a FC/ESC stack from here, a set of motors, and the Umma85 kit, and you'll be on your way to creating your Naked GoPro cinematic adventures. 

We suggest going with the 85 size if you're priority is to have the smallest footprint possible to hit the tiniest of gaps. If you need more power though, check out the 95.
