I'm looking to use the XR5 module for a high altitude flight. Have you used it yet for your video application? If so, was it successful and would you recommend the XR5, with regard to data rate and power consumption? I assume the transmission range is acceptable :)
How are the performance of these units? I've experimented with 802.11n wireless already and it gives great quality video, but the frame rate can dip dramatically when there is bad interference or misalignment. Do you have any video samples?
