I saw Feiyu tech people working and testing this quad a while back. I am happy finally they released it. Saw it in action, what a great quad it is. Its here with me now. Needs a bit of work to build it that I am willing to do with soldering too and I am sure its worth it. This is unboxing video. Probably will try to do the build video too and then flight videos. I am expecting much better performance on this quad for my FPV and AP needs. Thanks FeiYu Tech for a great X4 quad.
