Would this thing even be considered a "helicopter"???

I don't know, but if I were to guess, you're right.

Scorpion1alpha-
It's an Israeli drone with twin fixed-lift rotors and the two rotors in back can swivel. It is considered a helicopter.

Very similar idea to:

There weren't many pictures on it to see the default cant of the two main rotors. I assume they are rotating in opposite directions to counteract torque.

Bell's EDAT Tail Rotor should be a interesting solution.

Testing for the next generation of turbine engine that will replace existing helicopter engines and will be used in the FARA and FLRAA to begin soon

No more T700s? No way.

Stand by for acronyms:

The T901 was the winner of the the competition for the ITEP (Improved Turbine Engine Program). It is the engine Army required the FARA bidders to design their aircraft around. In addition, it is planned to replace the T700 in UH-60 and AH-64.

It is too small for FLRAA. The engine the Army was going to develop for that is FATE (Future Affordable Turbine Engine). It may also replace CH-47 engines. Originally Army specified that FLRAA competitors must design around the winner of that competition. However, Army's schedule for FATE does not match that of FLRAA, and it may not be ready in time for initial production of FLRAA. Army has released Bell and Sikorsky from that requirement, at least for EMD and initial production. Bell announced some time back they're going to use the Rolls AE 1107F, and later Sikorsky said they'd use the Honeywell HTS7500.

The future helicopter engine for the US Army is starting its first real testing

Both Sikorsky and Bell's FARA design is almost complete

Both looking good. Personally, I'm still pulling for the Bell's design.

Army earlier had hoped to accelerate ITEP/T901 development by a year to get FARA operational sooner. Unfortunately, due to COVID and some supply chain issues, that didn't work out. Although FARA has slipped from previously announced schedules by about a year, this only puts it back on the original schedule rather than the hoped for accelerated one.

If Bell Invictus wins I'd hope the Marines carry the design forward as a Cobra replacement. The Valor is simply too big for the role. The Sikorsky model might make for a nice Sea Hawk alternative.

That is SEXY. Must admit, it looks a little preggo in the middle though. Sleek, simple and compact otherwise. If looks alone wins, I like the Invictus's chances.

I fully agree that the Invictus's is the best looking of this competition and it's my favourite hands down.

It kinda reminds me the Comanche which IMO should never have been cancelled so I consider it to be a kinda of a "Comanche reborn" (but being different, of course).
“Active stealth” is what the ignorant nay sayers call ECM and pretend like it’s new.

My money says Bell wins the Blackhawk replacement, with the V-280, and Sikorsky gets FARA.
