NOTE: 3DRobotics ceased production of their telemetry sets in their Tijuana factory in December 2015 and discontinued their own branded radio sets. At Kopterworx we tested different OEM version radios from different vendors and choose one, which is 100% compatible and works without any problems. All radios are equipped with two sets of cables - so they work out of the box with original Pixhawks and with compatible FCs.
