As I recall, the transition to thrust augmented flight was relatively benign. For takeoff we set the collective at approximately 25-30% then performed a traditional airplane takeoff and transition using the thrust from the J60s. As the airspeed increased the Q from the PT-6s decreased to 0% and the rotor speed settled in at 88% with the freewheeling units disengaged. The transition from for forward flight was just as benign. We reduced the thrust from J60s. As the airspeed decreased the PT6 torques increased to bring the rotor speed back to 100%. We then adjusted the collect and proceeded to fly a traditional helicopter. All and all, an easy aircraft to fly. Back then I would have rated it an E ticket ride.
