Looking to replace the blades on a 1 Pro. Saw on Amazon that the blades for V2 work with the V1 Pro and visually they look the same. Ordered a set from B&H, #DJI12P61QRP, they don't fit.... There is a very slight difference on the bottoms where they mate to the motors and the quick releases won't close. The quick release is the same style mechanism but different enough that they don't work. Looks like the ones I got are 1550T and looks like what I need are 1345T. Sound correct? TIA
