Caution: the DG-1000T is equipped with a powerful longitudinal trimming
device. In addition the mass balance weight of the elevator is incorporated in the
elevator control system. Due to these facts the elevator control forces during
inverted flight change considerably with trim position.
It is strongly recommended to trim the glider to approx. 140 km/h (76 kts.) in
horizontal flight prior to executing aerobatics, especially prior to inverted flight.
