Hill Helicopters HX50
Griphorns, in general, can be problematic even when made of proper hand forged and peened material. Hill's overall setup seems to be copying Hughes 369/500 though without lead-lag discrete dampers or tying strap packs to opposite side blades (so more like AH-64).
With regard to the head + sail fairing, this is a historically tough nut to crack - particularly in a volume production application. At Sikorsky, it was found to be difficult to maintain the close clearances (Hill mentions 10mm in his patent) and even in the end abandoned on the one-off X2 tech demonstrator.
Personally I'd like to see some...any...info on the real blades as that is my wheelhouse.

there are no blade retention loads in the grip only pitch change and pitch bearing axis
Mate found that out in a 205 that ended with a ditching (fixed floats) because of vibration. Blade grip had cracked circumferentialy the full 360° so the only retention was the tension/torsion strap. On shutdown the blade drooped to the extent that it was punctured by the roof mounted VHF antenna. Grip had been supplied as new where as it had somehow snuck back into the distributor supply chain when it should have been scrapped after running out of hours.
The design is question is similar to the H500 - there are no blade retention loads in the "pitch housings".

In the meantime, I'll hold onto my 206, if that's OK. At least I can actually fly it, not just gaze at a poster and touch myself! I've talked to lots of other JetRanger owners and none of them are even interested in the Hill. Go figure.
Easy to get trapped by getting wedded to an initial position and then either becoming overly optimistic or negative. Outside of the opportunity to make money or not out of trading a place on the order book the prospect of actually flying a customer aircraft (and remember the HC/HX distinction) stated deliveries is 2025 (and that in itself gives a 12 month window) and I don’t think Robinson or Bell need to fear much this decade.
It's like the Time Warp except there is no step to the left before a jump to the right.
No engine run in 2023? Let's do the Time Warp again.................

Or indeed a jump to the left before a step to the right as I am sure someone will point out
