I needed a small quad for indoor and backyard flying, and I really liked the style of the Hoverbot. The biggest problem during the build was the brittle wires of the motors had a tendency to snap off at the tiny soldering points - it's definitely a good exercise in precise soldering. The stack is also a little higher than I would have liked, and because of the way the Micro Lux/4-in-1 ESC is oriented, it makes the most sense for the battery lead to stick out the front. I could have oriented it slightly differently, but it's a small cosmetic thing that I can live with.

It flies fantastically - tons of thrust with 2S. Eventually I'll go for 3S but I'm very happy for now.

6/13 Update

I've replaced the motors as first pictured. It turns out that running propellers on a friction-fit motor is a horrible, horrible idea. No amount of dental floss or superglue is going to create a perfect fit. I dumped the Racerstars and went for the AirbladeUAV 1103s which I can't recommend enough - they have mounts for screwing in props, and also use flexible silicone wires which are super easy to work with. I've also dumped the original Lumenier AIO Cam/VTX and opted for a smaller, hopefully-more-durable VM275 variant. I had two Lumenier AIO Cam/VTX die on me for mysterious reasons; and will not give them another chance. The smaller VM275 mounts nicer anyhow, with the Hoverbot cam mount.
