This is a quick comparison between the Chinese DJI Style QuadCopter arms. There seems to be a variety of them on the market and its very hit and miss as far as what people get from different Chinese Suppliers. The arms that came with my quad were fantastic but the spares I purchased were very soft and realistically not usable for videography.
The DJI Genuine Arms are miles ahead of the the copies. Just keep in mind the chinese copies are going to be hit and miss. I think I was just lucky with the quad I purchased.
