What maneuverability?

From "Spyclip":

https://www.secretprojects.co.uk/thr....13812/page-46

"I can confidently say that there have been a total of zero published flight demonstrations where level 1 handling qualities were demonstrated with requisite rates in pitch, roll, or (particularly) yaw on any ABC aircraft historically.

If any of these had been accomplished over the Jupiter swamps with Raider I would eat my shoe if Sikorsky would decline to publicize such footage.

The fact that the V-280 was able to perform these maneuvers at double the gross weight of S-97 makes the ongoing ad nauseum Sikorsky marketing of mythical extreme rigid rotor agility that much more egregious.

All of this is to say absolutely nothing of SB1's lack of demonstrating anything of note whatsoever."

A "feature" of the Kamov is that the rotors occasionally hit each other:

The Raider and Defiant are more complex than the Kamov Alligator. They have a very large pusher prop, some say the largest prop ever produced in the US for Defiant. In a fast maneuver, there will be large 1-P moments input to the airframe. The control system must account for this, which may be ?impossible?. Note the AVX proposal had two ducted fans, so would not have this problem.
