Okay, this one's just kind of crazy. It's loud, inefficient, and persnickety. You only get about 3 minutes of flight time from a 2200mAh 3S battery. So if that's your bag, this is an aircraft for you!
It uses the top & bottom build plates (and modified cleanflight firmware) from Excelsior Bravo. (http://www.thingiverse.com/thing:825920)
EDFs are EDF55 with H300 Motor from HobbyKing
ESCs are Afro 20A
Battery (as shown) is 2200mAh 3S. (May not be the best choice.)
Cross tube is ~124mm
Rear tube is ~200mm
If you build one, God have mercy on you. :-P
Update- It seems to fly better with a 1600mAh 4S battery:
Use nylock nuts on the EDF mount rings, and don't tighten them down all the way. (Doing so flexes the housing enough to make the impeller bind.) I backed each one out until the impellers didn't scrape.
