I recently bought this set, and couldn't be happier with them. One did arrive with a broken main rotor (snapped at the shaft) but the part is so tiny, there isn't really a reasonable way to combat that issue. I tiny dab of glue, and it was good as new, and actually made painting the model much easier, as I didn't have to worry about the rotor being in the way. I may actually snap the other off myself to help with repositioning and painting, then reattach it with a pin. This isn't a complaint, I am 100% satisfied with the model. I think of it as more of a heads up, combined with a happy accident to make it much easier to handle in the paint and finish portion. Just my 2 coppers worth.
