Correct. A very high performance aircraft that is also very demanding of the pilot.
The performance is compelling. But a lot of good pilots have gotten behind when operating this aircraft.
Had never heard of this airplane before. The following from Wikipedia is scary and I don’t even know for sure what all of it means:
“The MU-2 has performance similar to a small jet; however, as it weighs less than 12,500 pounds (5,700 kg), under U.S. pilot certification rules in force at the time, a pilot holding a multi-engine rating for much slower light twin piston-engine aircraft was allowed to fly the MU-2 with only a simple flight instructor endorsement. Inexperience with the MU-2’s higher speeds, altitudes, and climb and descent rates resulted in many crashes.
“Standard engine-out procedures are counterproductive when flying the MU-2: the commonly taught procedure of reducing flap following an engine failure on takeoff leads to a critical reduction in lift in the MU-2 with its unusually large and effective flaps. ... Additionally, the MU-2 is sensitive to trim settings, and it is critical to promptly trim the aircraft properly in all phases of flight.[4]
“The absence of adverse yaw eliminates the need to use rudder for coordinated flight, but proper and prompt use of rudder is vital to counter the aircraft’s tendency to roll in reaction to engine torque; at low airspeed, the aircraft will rapidly roll and enter an accelerated stall if the pilot applies full power without adequate preparation...”
