While mainly working on bigger copters, I decided to build a tiny one to fly indoors. It is definitely not suitable for FPV racing because of the range and video latency but is pretty just for casual flights for pilots like me.
At first I tried to use iNAV but later switched to ArduCopter and managed to tune it somehow, so now stabilization is acceptable for me.
