QuadA2012: MD540 makes its debut - News - Shephard
It looks like it is an MD530FF airframe with a new engine, six-blade main rotor head and a beefed-up set of skids. It doesn't seem to have a four-blade tail rotor, yet. MDHI still haven't decided if it will be certified for civilian use or if it will remain a military aircraft only. In the military configuration shown here, it seems to be packing a similar weapons load to the AH-6i with Hellfire and DAGR rockets so it seems it will be a capable light attack helicopter for a price that might be cheaper than the Boeing product. It will be interesting to see its lifting ability if it does go on sale to commercial operators.
