Very impressive price. Shipping included. I would assume that those are not copies, but the real receiver? There is a warning on the Spektrum site about some copies floating around for cheaper price. Probably on eBay rather than a site like this.

Note that I did have a real AR6100 fail on me and almost ruined a plane (I have 6 of them - 2 year old or under). The Orange RX have not failed me yet (only 3 months old)
