Hughes - I am quite aware of the costs of spares and how much the manufacturers profiteer on them but I'm not sure how that makes this innovative design (for which we can't see any pictures or have a description) the new sliced bread of the helicopter world.
Designing your own gas turbine would be expensive enough and the latest composite materials don't come cheap either - an old schoolmate has his own company that specialises in them.
I presume all the secrecy is because they don't have the patents approved yet.
However, if it is as good as you say and the price is right, I may well buy one
