Full disclosure, Iâm very new to building UAVs (this is my first build on my own ).
I got a Pixracer R14 for an early christmas present, and wanted to hook it up to a Spektrum DXe with an AR610 receiver. They were able to pair no problem.
When I try to perform radio calibration in QGroundControl (daily build, downloaded yesterday), I get the error: âDetected 0 radio channels. To operate PX4, you need at least 5 channels.â The receiver is connected via itâs AUX port to the pixracerâs RC port, using the supplied cable (the one with the loose RSSI cable).
Am I missing something here? Is there a PX4 parameter I have to set, or a pin that needs to change position? Both mrobotics (where I bought it) and pixhawk.org claim that itâs DSMX compatible.
If theyâre not compatible, would buying a PWM to PPM converter be a cheaper option than buying a new controller/receiver?
