Well the Fledermaus and the Striker will defiantly have something to fear when Bellowing Bertie takes to the skies later this year. Move 3, and 7/1 against all other aircraft.
Updated: Now we have a new look at Diving Dotty, and some of her stats, she looks to have bombs slightly more powerful than the SSU, which can be a little better then their Axis counterparts.
Close examination shows the bombs to be most likely 500 lb. bombs with 2/+ for infantry 1-4, and 2/skull for ground vehicles 1-5. Vehicle class 6 and 7 are not visible.
