Detailed Description

DtFallingFromSkyActuatorComponent provides a simple, kinematics-based model for air motion based on throttle, stick, and pedal inputs.

End User Description: DtFallingFromSkyActuatorComponent is based on the original DtFallingFromSkyActuatorComponent, but instead of stick and pedal control values causing changes in rotational acceleration, in this simplified model they effect changes in rotational velocity instead. So 0 x/y stick and 0 pedal will result in no rotation of the airframe.

Uses Descriptor Type: DtComponentDescriptor
