First of all, the flight model of this add-on isn't exactly like the real thing; it's better :-) To date, the real Xenon gyro isn't able to do true VTOL, nor is it able to perform zero-airspeed hovering or jump-takeoffs. But this expected to change in the near future, like already seen in e.g. the Carter Gyro Demonstrator. This FSX add-on however, already anticipates on that :-)
