My application requires flying in Auto or Guided. it will be exclusively BVLOS over 4G. (I know you usually shouldn’t, but I have permission and a restricted airspace.)
This means that I don’t have any use for an RC receiver. I would actually really prefer to not have a receiver, because my safety case is based on minimizing weight and since it won’t be used, it’s a liability, an unnecessary link in tha chain which could fail.
So my question is - is this possible? I know px4 has COM_RC_IN_MODE (https://dev.px4.io/en/advanced/parameter_reference.html)? where you can chose wether to use RC or not.
In my own testing on a flying wing I can happily fly with the RC transmitter turned off as long as the RC receiver is plugged in. But if I remove the receiver the elevens act strangely. The left one seems ok, while the right one is turned way up. I have tried trimming the servo outputs to a setting where on the ground in FBW it looks like the elevens are operating about right if I turn the plane about it’s axis. But when I try to fly I get a lot of turning and a lot of rolling and then inevitably crashes.
It was suggested on the developer Gitter that RC_CHANNELS_OVERRIDE might be used, but that seems to have to do with using a joystick?
I would really appreciate any suggestions or explanations!
