Problem connecting Pixhawk and Futaba receiver

Hi

Two of my customers have trouble setting up the Pixhawk - I myself have a Pixhawk, but don't use a Futaba receiver, thereby I can't replicate the problem (I would like to find out if the problem is connected to the receiver they use, or something else).

Both use a Futaba R7008SB receiver.
Both managed to upload the Firmware to their Pixhawks - but they are not able to do the radio calibration (the Pixhawk doesn't "see" the receivers, the bars in the calibration are all grey).

They have nothing else connected to the Pixhawk, except receiver (connected to the right port / RC), buzzer, safety switch and USB cable.

The Pixhawk signals via the big LED "pre-arm check failed" (which makes sense ;)

They power the Pixhawk via USB and at the same time with a LiPo (via the Power Module).

The receiver is "found" by the remote, the LEDs are on, the setting of receiver and remote (regarding the use of the SBUS) seems to be right. They use the right port of the receiver to connect to the Pixhawk.

I am happy about any suggestions ...

Thanks a lot in advance

Felix

  • Have the same problem with the same receiver and a futaba T14SG. I would appreciate any help. I connect my rx  from pin8 to RC pin on pixhawk but not recognized :(

  • Shouldnt it be on SBUS  not RC BTW?
