    Hello

    Very weird problem.

    Using the Voxl2 mini. We are able to arm the drone. The motors respond to Yaw, Roll, and pitch as expected, but do not respond to throttle. We double checked the radio calibration and the can confirm through QGound that its receiving throttle, but it's not being output to the motors. We have tried multiple flight modes (manual, stabilized, altitude) and still no motor output when sending throttle.

    Any help would be appreciated

    Thanks

          @Eric-Katzfey here is the log, and we are using the Radiomaster Nomad dualband. I will say the TX is on ELRS 3.6 and the receiver is on 3.5.3, but the Nomad's 3.5.3 is wonky.

            @jeremyrbrown5 It doesn't look like there is any problem with the RC. The log shows the throttle stick being moved up. And it shows the motor actuators being set based on that throttle input. But, for some reason, the commands going to the ESC are all 0 so the motors don't spin. It kind of points to a configuration issue but I'm not able to see anything obviously wrong in the parameters. Which ESC are you using? Is this in a custom vehicle? Are you using any of the px4 parameter sets from the voxl-px4-params package?
