    No doubt my underlying desire for Boeing to be successful, LOL, in any regard while I like the Osprey, I think the single mast contra rotating Bell Defiant is an amazing machine, that is technologically and operationally less risky, but hey, what do I know?? LOL

    I won't say amazing, since its NOT! the Valor is a fixed wing, vertical take off and landing turbo prop aircraft, that's what it is, I used to fly a 1980 Mitsubishi Marquise that would cruise 250 knots easily, and the A-400 is much faster, so turbo prop fixed wing aircraft are "very fast"... the V-280 is a tilt-rotor, or just larger propellors, as such it has some technical issues and difficulties that will never characterize the Defiant, which is still a helicopter with contra-rotating rigid fixed rotor blades.. and a pusher propeller to increase VMAX....

    So the Valor will NEVER be as nimble and maneuverable in the low speed regime as the Defiant, the Defiant will NEVER be as fast as the Valor....

    I really question the Valor as the Army, Marines vertical lift platform, I know the Marines LOVE the Osprey, but I still think a troop helicopter for rapid insertions, still needs the Defiant's terminal maneuverability.....

    At this point neither is really all up and ready. Some people have been pushing to cancel the program right now and buy V280. The problem right now for that is that V280 and Defiant lack a critical feature there final engines. Valor and Defiant are only as yet Tech demos.
    Without those engines either the T900 or T901 neither form has the range of the FVL requirement.
    Both have potential for use and I think the best outcome for the US DOD as a Whole is some combination of both configurations a Raider derived FVL capability set 1, perhaps a Valor based Cap 3 some true future attack platform. And a Tiltrotor based Cap 4. The fight is when the USAF and US Army start to fight over cap 5. Cap 5 was FVL Ultra which aimed to try and punch a C130J sized transport. That’s Airforce Turf and the USAF seems to want a Jet for that.

    (1)twin helicopters can be quite nimble. Thus there are no physical restrictions stoping tilt rotors from being nimble.
    (2)compround rigid tilt rotors aren't just improved tilt-rotors, its more complex. Importantly, it's precisely low-speed handling of rotor blades which is being compromised for the sake of higher speed.
    (3)Defiant is 'uge for its applications. It may not be obvious from its appearence, but payload volume is forward from the rotor mast. This thing dwarfs blackhawk.

    So, frankly speaking, defiant, a piece of art technology-wise as it is, is a very complex pick.
    And tbh, i see valor as better

    No it doesn’t it’s actually almost identical in size.

    Compare aircraft bodies, not just dimensions(i.e. area restrictions).
    Dimension-vise even v-280 ain't special.
