The increase of main rotor diameter and the addition of a third engine aft of the main gearbox had a problematic impact on the aircraft's center of gravity. To offset this, the tail rotor diameter was increased. The vertical stabilizer was also canted 20° to the left, allowing the tail rotor to generate an extra 2,000 lbs of lift.
