After getting the HobbyKing MicroQuad put together rather nicely, I was having a lot of problems with one of the motors running erratically. I thought it might be a problem with the motor or ESC, but Andreas suggested swapping out the KKBoard and seeing if that would help.
We swapped in his APM2, and it flew rather nicely, modulo some PID tuning to get rid of the shakes.
Impressively, the APM2 is almost the same dimensions as the KKBoard. As far as I know, this is the smallest quad that's run with the APM2, but I'm happy to receive any corrections.
I'm rather encouraged, it will be a lot of fun having a tiny platform that I can fly indoors!
