The absolute worst part was popping the clips for the top cover. The arms were okay, but the ones on the main body area were a pain. Screws all came out pretty easy - I made notes and took photos of what screws went where. I did a full disassemble, so the only masking I did was the antenna coax where they exit the landing gear at the top (left the antennas in the legs for painting), the gold Phantom emblem, and the LED light pipes on the battery caps. Oh, and there is a small light pipe on the VPS module cover. Anybody know what the button and LED on the VPS module are for? Assembly was a snap. Get it? Haha All screws went in fine, cables were good, no issues at all really.
