Very nice! But I'll have to, according to @Atrik, gigantically troll you (never my intention really, I just happen to be like this ) and point out that the tail rotor is spinning in the wrong way, not just because vectors would be inverted when compared to the main rotor (although maybe some models designed are like that?) but because of the blades themselves, they are rotating backwards (careful when you see them in a video already spinning, as we all know, things that spin fast can seem to spin the other way).
