Just saw this from Gaui and very excited.
With all the benefits of a Heli over multirotors in large applications (Efficiency, payload capability, safety (ability to auto-rotate), etc.), I think this is a great step forward in finally having a mass produced option for a Heli configuration. Hopefully it starts a trend and some of the other heli manufacturers jump on board as well. Maybe, if more and more start using heli's it will help give Rob a few more tests for Arducopter Traditional Heli as well to further advance the firmware along!
