Oh well, I need to get another quadcopter's flight controller configured, and then sent out on its maiden flight...
Maiden flight completed without incident*.
All things considered, though, I've rather be fixing TBE

*ignoring the fact the new transmitter I bought for this is faulty (no sound), so rebound to my other. Bit of an arse, as to get to the receiver to rebind means a bit of a strip, and will have to be repeated when new xmitter is fixed.
