I've been looking for a good flying tiny quad for indoor use, and had a chance to look at (but not fly) Chris's Ladybird. I've been waiting for a sign as to whether or not to get it, and here it is. I know other people here have been looking for a good quality small indoor quad, so I thought I would mention it here.
I'm interested in the included transmitter, which includes two-way telemetry (not supported by the Ladybird, as far as I can tell). You can get it with either a Mode 1 or Mode 2 transmitter, or as a bind-and-fly if you already have a Walkera.
