The video is mildly interesting even though it is two years after the scheduled closure of the demo phase of FLRAA program.
On the claimed 236 knots level flight speed: Was it near max gross weight to simulate a real mission? Was power used at or less than max continuous? What was the aircraft’s range in tested configuration? How was the vibration? As stated previously Bell flew a modified short cabin Huey to a level flight speed of 274 knots (addition of two turbojets). In this configuration the aircraft had near zero range, no useful payload, and had brutal vibration levels.
As to the other achievements the maneuverability looked very sluggish and the ability to hover near trees is a feature of every vertical lift aircraft.
