Radio-controlled helicopter manufacturer Hirobo has developed a new full-size helicopter, the Hirobo Bit.  Shown at the recent Japan Aerospace show, the all-composite helicopter was shown, although no videos are known to exist of the aircraft in flight.  With an electric engine and coaxial rotor system, Hirobo expect this to be a very quiet helicopter, although no details of the powerplant were given

The company is not expecting to deliver the passenger carrying varient before 2021, citing expected bureaucratic problems.  Prices quoted are 10 million yen ($125,000) for an unmanned version, or three times that for one carrying a person.  The unmanned version is expected much sooner.
