None of the tilt rotor heads that I have experience with has a dramatically higher flapping capability than the V-22. Certainly the two production intent designs flown after the V-22 don't.
True, I should have said "design studies". In fact, remember that 609 has no lateral cyclic flapping, and gets roll through DCP in hover and flaps almost identically to the V-22 despite not being underslung.
So if there's enhanced low speed maneuverability, it isn't coming from there.
'Sports-car' Performance Promised for Bell V-280 | Defense: Aviation International News
The Army wants to focus on low-speed agility, so the V-280 will have about 50 percent more flapping capability in its rotor system than the V-22. That’s going to enable an even greater level of agility in all axes–pitch, roll, and yaw–so that you have that sports-car type of helicopter performance in the landing zones and objective areas. That’s a focus for the Army customer.
