Convert OH-58D's to OQH-58D's, using a lot of MQ-8C hardware and design?  There was also Bell's OH-58F proposal which added a more powerful engine (essentially transplanting a lot from late-model Bell 407's) and used a new sensor turret under the nose.  At least one demonstrator with uprated engine flew (I had a very small part in designing that when I first came to Bell).

Hey, Carl how about we rename this thread to something along the lines of OH-58, Bell 206/407 etc. and related.

Sorry Jon. I always get major brain malfunction when it comes to you and Jeff.

What about a 607 with a NOTAR or ducted rotor?

BTW, AVX was founded by a number of disaffected former Bell employees.  The upper management type responsible for their disaffection has since "decided to move on to new challenges".

Biggest problem I see with their proposal is that you are going to need a radically new transmission to handle the new demands and I question just how large that's going to be, unless you are also going to fly-by-wire controls for the rotors.

Isn't moving the sighting unit from mast top to chin a downgrade, really? The whole idea with the mast-mounted sight being that you do not need to expose the rest of the chopper, but can hover behind treeline with only the sight visible?

That was the idea when the main theatre of deployment was Northern Europe.  The locations where they have actually been used have shown that it's not a useful concept in much of the world, hence the US Army's desire/request for an under-nose mounting.

MQ-8C, when you just don't want to mask.

Nice photo, though that might get messy if they don't retract before landing

Interesting, is that an ASM or a mine-sweeping device?
