I think this is the most interesting long range system to date. It has 20 channels so you can connect two completely different radios to it at the same time and use one radio and operator for the flying of the vehicle and the second radio and operator to control a camera gimbal and camera. The receivers for the two radios stay on the ground station and the vehicle only carries the one 20 channel receiver. The on-board receiver has a built-in signal strength meter and signal interference meter. How cool is that? It also seems that the 30 km rating is conservative as one owner mentioned in another YouTube video that in the high power setting he thinks he could go 60 miles.
