I am currently working on a project that will be a flying device, so i require a bit of range for control. I have been looking around for control systems, and have come across the XBee-PRO 802.15.4 RF Modem, which seems to me to be the best solution for me. Has anyone used this device before? If so is it reliable? Good for the price? Range? Would you recommend it for a flying device? And how on the other end of this would i control this device? Any and all information is greatly appreciated.
