As Dave says, my aim is to keep the cost of the system as low as possible. While I would agree that a fully integrated system would be the neatest solution, e flybar is still in its infancy and the current approach of using separate units has many advantages:-
The mixer is low cost and applicable to a flybar equipped ccpm heli so does not constitute a big investment to the pilot wishing to try flybarless. For someone wishing to go flybarless on a non CCPM heli (say Raptor 50) they don't even need to have a mixer! Likewise, although two 720s is not an inconsiderable investment they are applicable to the tail so someone deciding that flybarless is not for them can re-deploy them on the tail of their helis or sell them on to others for that use.
Because the main rotor has considerably greater natural damping than the tail it is not as reliant on servo speed for a satisfactory electronic control system. Indeed, we are finding that the facilities designed into the 720 gyro to allow it to provide accurate control of the tail are (with just changes to the settings) well up to the job of controlling the cyclics.
Best regards
