[Update] This thing unfortunately was one of the victims of the recent “catastrophic hardware failure” at Thingiverse.com. It used to be "thing:4811", now it's "thing:4812" :)
I'm not sure if it's possible to recover the comments on the original thing (as far as I know, the comments section is outsourced and not part of the thiniverse servers).
Also, the "Likes" are gone... Do you still like this thing?

Since the original frame of my Gaui 330XS Quadrocopter was damaged in a crash, I built a new frame from scratch, using printed plastic parts.
The four arms are 10x10mm wood profiles (cheap, sturdy, light weight). The motors and electronics are cannibalized from the crashed Gaui Quadrocopter. But it should be no problem to use other motors and/or electronics for this.
