The MD 530 F is a hold out from the price jump. No irritating Fadec or $18K Litton gauges. More seat room than a 407 in front.
The vendors got screwed sooo hard by the older MD operation. They saw red when the idea of supplying MD again was offered.
With high certification costs all rotorcraft are only slight changes on older Designs. The 530 F could run 15 -20 lbs more torque according to the Factory pilots, but again certification limits its performance.
Most innovation is limited by certification cost and or liability. Unit sales to break even, don't justify it .
MDs have a limited mission role.
