Your drawing might not be too far from the truth. Here is what Lynn Tilton has to say about the MD540F.
""Tilton said the company’s next innovation will be a glass cockpit for the MD902, and she added that Garmin is among the companies working on the upgrade. MDH will also introduce a new aircraft, the MD540F, a hybrid of the MD530F and the MD600, which will occupy a sweet spot in power and performance between the two models and is expected to have more appeal in the marketplace.
The MD540F will be aimed at the foreign military market and at domestic EMS helicopter operators. “The cabin is perfect [for EMS] and it’s a little more easy to handle” than the MD600, Tilton said. “It’s something we can do in the short term, because they’ll be made from pieces of our [current] aircraft.”"
Will a conventional tailboom and possibly longer main rotor blades turn the MD600 into a successful design?
