This is a continuation of this github issue: More than 8 rotors using multiple Pixhawks/Aux channels · Issue #7116 · PX4/PX4-Autopilot · GitHub
I’m building a a coxial dodeca (12 rotor) copter. I’ve written a mixer for it, so the AUX channels mix the bottom half of the copter and the MAIN channels mix the top. It seems to work great, and I’ve run it through 10 batteries. I want to know if anyone could point out any potential issues with it, and how to test them, so I can further vet the prototype.
