I really, really, really want to build a Y6 copter. It's technically a hexacopter, but honestly it looks more like a tricopter. I'm also not quite sure what extra rotors do for you, but I'm sure there has to be documentation somewhere. I feel like if one motor were to fail, you might get better compensation/not fall to a miserable death, but otherwise, it looks like it'd have less lift that a X6 hexacopter. Regardless, I really like the Y6 design aesthetic (I know, I know, but it's the fashion side of me talking), and I'd much rather build a pretty thing if I can.
I might cheat this time and start with ArduCopter so I don't have to come up with the controls by hand. Bad part is that a nice ArduPilotMega Board is expensive, but then again I don't think I'll need the GPS, barometer, etc. However, a toned-down version is still pricey. The main reason why I'm considering ArduCopter is because the software advertises itself as already set up for Y6 configuration. *Sigh* I really should just man-up and program it myself...but I'm burnt out :(
Also, lookee here!
Now that's magic. He is cheating a little with motion capture camera feedback rather than a true on-board PID, but nonetheless, it's awfully impressive. My new goal is to have Babycopter balance a broom before I graduate. Not too lofty of a goal, eh? :P
Oh and one last treat before I become too busy again.
