It's probably coming, but in Europe they've launched both the motors and the ESC line under the O.S brand. O.S and Futaba are probably owned by the same company. I love O.S and would use that ESC in a heartbeat, but it seems a bit heavy? My Kontronik jive 80 weighs significantly less.

BTW, What Osiris prototype? Pics of the whole plane, please [8D]
