No, it's not new. It's just impractical. The blades are in different planes, and I've spent weeks trying to get one smooth enough to be acceptable. You can't really track them, you just get them to an acceptable ride. The first ones came out without the weights on the head, and most couldn't be tracked at all, so Bell put a couple of hundred pounds of weight up there to make it work, and that was payload lost immediately. The 412 is just a UH1 with 2 engines and a slapped-together 4-blade system, nothing new about it. Bell is so far behind the rest of the industry it may never recover.
