Spektrum 18 QQ Transmitter, (No. 9,) AR 9020 Receiver, and a R 1221x receiver, Charger , and Custom QQ case Radio has worked perfectly since new.
This radio is an upgraded signature 18 designed by world champion Quique Somenzini, Horizon /Spektrum built 2000 copies, this one is number 9, has same software as all Specktrum radios and has been updated to date. I understand the QQ has special gimbals different than the original 18. Has Lopo battery and Telemetry,does not have voice command.
