Surely if Bell had introduced an all composite fuselage, with soft-in-plane composite rotor and carbon blades he would have slammed them just the same for building something so expensive and out of touch with the market. The NRE and certification of a new dynamic system and blade would have probably doubled the cost alone
Take the Marenco SKYe for instance. It has a composite fuselage and new 5 bladed rotor and a lot of other innovative stuff. Looks good and looks like a good helicopter. Projected cost $3M+, only 50 orders and it's been on the drawing board since 2007.
