This is FUD. Skydio has produced and sold amazing drones in the US for several years. Both are invested in by Andreessen Horowitz and Palmer almost certainly knows about them.
> Ghost is a single-rotor aircraft. The mechanicals of the rotor system are harder to design and manufacture than a DJI-style quadcopter, and flight controls are harder to program, but the result is much lower aerodynamic disk loading that results in longer endurance (over 100 minutes with real mission payloads), near-silent acoustic signature, high max payload capacity (dozens of pounds), and high speed. Compare this with a DJI Inspire 2, a high-end offering that costs $3000 that can lumber around with a couple pounds for 24 to 27 minutes, props screaming.

At least it does not require a mandatory PID control to not fall out of the sky.
Very little math involved in control of a helicopter. A 3 actuator type with 1 actuator for each axis basically has no need for any control signal manipulation, and can be made fully analog.
And a helicopter can be made more or less statically stable by pure mechanics, and aerodynamics.
P.S.
It doesn't seem that the drone in question exist in anything, but CGI at the moment.
P.P.S.
And quite unsound CG at that. On some of their CG shots, a swashplate actuators are attached with their axis coincidal with that rotor..., and a tail rotor control yoke not attached to anything...
In my understanding Ghost 1-3 do exist, but classified.
Ghost 4 is in development/entering production. Being military project, it is likely that publishing real photos would be difficult at this stage for various reasons. Same with giving real blueprints/CAD files to a 3D artist for marketing materials.
RC Heli = expensive specialized mechanical parts, collective pitch Rotor Head is a nightmare.
quad = difficult to develop software control loop
One is easier to replicate after initial development than the other. Heli crash also usually results in destruction of Rotor Head, the most expensive part. You could use an analogy of Carburetor versus EFI.
Interesting, thanks. I've never heard this perspective before. So you'd say that anyone building an elaborate homebrew quad -- e.g., the TechIngredients guy at https://www.youtube.com/watch?v=4ZPvZiJLbvI , who generally seems to know what he's doing -- would be better off putting comparable effort (and comparable cash) into a single-rotor aircraft instead?
Actually reading the post would tell you that he means that Anduril just released best Inspire-sized drone for military use.
Skydio is great drone, but it is toy-sized plastic drone.
Specifications of the Ghost 4 are really impressive: 100 minutes flight time with couple pounds of payload powered by standard Li-ion batteries, rugged design and materials, low sound signature and thin visible profile, on-board AI, swarming, autonomy, etc.
