I have been trying to setup a Rise RXS255 drone. I am using the LibrePilot. I can get as far as up to Stick Calibration. Nothing happens when I try to calibrate. I am using a Futaba 14sga Transmitter. I tried using a Futaba R6006FS and a SBUS receiver R7008SB. The Tech at Hobby Services is out sick. Any help would be appreciated.
