After building a bunch of little fast quads, I have wanted to build myself something bigger that has some enclosed space to work with. The idea of Darth Hex came over a year ago when I saw a Disney popcorn bucket in the shape of Darth Vader's head and bought a couple of them on ebay to figure out later.
The frame is just a basic Turnigy Talon Hex, nothing special there.
The problem is that for a much larger hex, the parts get a bit expensive, and I just didn't want to spend that much. The solution was when I found some insanely cheap motors on Amazon which only cost $25 for four motors and propellers. I had to try them out. I built a large quad which tested out ok, and so I bought a bunch more and began to build Darth.

Currently my go-to ESC for everthing has become the DYS BL20A, which is both powerful and inexpensive.
Inside the skull holds Darth's brains, in this case a Quanton FC. I've had a bunch of issues with the Quanton trying to get it functioning with the right firmware, but it seems to be working at the moment. Haven't gotten all the features up to speed, but one step at a time...
The receiver is a FrSky D4R-II, outputting PPM to the Quanton. I have not yet been able to get RSSI working, as FrSky RSSI seems to not be compatible with anything. Additionally, Frsky hub telemetry has it's own issues, and I'm waiting to receive a TTL => RS232 converter to see if I can solve some problems.
Finally, I stuffed a bluetooth module in there for wireless access, and added a micro USB connector to the back of Darth's head, connected to the mini-USB on the Quanton. Makes it a little easier for those times when you actually need a hard connection.
The purpose of this whole thing was to have the large space to work future ideas.
First idea is to finish the connectivity, including RSSI and Frsky Hub Telemetry. I've got a GPS that I will be adding eventually, and eventually I want to add 3D FPV cameras in Darth's eyes, to see things from his perspective.
