Hello, I have a plane with a v-tail and I do not find in QGC how to activate the mix between track 2 and 4. Can you help me? Thanks
You should ask the firmware folks.
The albatross (airframe id 2106) is an A-Tail, but it's the same mixing.
If you want something more specific for your vehicle you could add a new configuration. Start by duplicating the Albatross. https://github.com/PX4/Firmware/blob/master/ROMFS/px4fmu_common/init.d/2106_albatross
Mixer documentation: https://dev.px4.io/en/concept/mixing.html
So if it is the same mixing, the A-Tail plane configuration should work for a standard v-tal without any other changes? Or is there something we have to alter with the mixing?
The mixing itself is fine, but you may have to flip servo directions for your particular configuration.
