It's so tempting to buy a Phantom 1.1.1. They're on sale for $399 new. I've checked and the NAZA has a PMU. I'd like to use the cheap Goodluckbuy gimbal and add a mini-iOSD without adding an upgrade board. Probably have to install can bus before mini-iOSD - and add FPV later. What is the easiest way to set up this config?
