There is nothing "new" under the sun. All the technology on this machine has been around for a long time and is all certified with the exception maybe of the 4 blade T/R setup running at higher speed. The 6 blades on a 530 was flown around 1997 which was when I saw it at Mesa as obviously they developed it before the 600N flew with it. Without extra tanks and with average reserves implemented around the planet, back of a fag packet calcs put the range with a full tank at about 140 miles? Lot's of skinny little blades will never equate to good hover or altitude efficiency due to parasite drag and poor L/D ratio as the AoA is not ideal. It will probably autorotate better than a 600 due to less fuselage blanketing but I would wager it will end up with a minimum weight limitation. The common denominator is you can only do so much if you start with the same rotor blade which has been around forever. If you need a "better" 530 this is probably the answer as it will be more "up to date". My two bob - for free!
