yea, it looks like they got some issues, the big 3 engine config is dicy on the scale up from the E...its gonna need more tail rotor, as they didnt lengthen the boom....etc...etc....it has about the HP of a mi26, but is 30 ft shorter...rotor is 30% less diameter.....why?? I wonder what they were thinking ...when you look at the 26, it looks more efficient in using the HP....so why pack 23000 hp in a helo that has no where the capability of the 26?....either in speed or lifting capability. max gross of the K is 85000lbs...vs 123000 for the 26....at virtually the same power.....seems the K needs a bigger rotor....a longer boom.....for starters...to take advantage of its HP....or stop the HP game and use 2 of the GE38's!...as with 3 engines and a 79 ft rotor....they are truly on the backside of the power curve......maybe LM bought a pig in a poke...as they bought sikorsky to sell this airframe....time will tell!!!
