The hover attitude (not angle of attack) is determined by the gear. As it has a tricycle gear the nose wheel must not hit first or even with the mains. So the hover attitude will be very similar to that used on a forward speed landing.
The angle of attack in the hover that necessarily results from the attitude needed will depend on the wind. In zero wind during the descent phase this could be as much as 90deg less any negative value cause by induced downflow from the lifting system.
