Custom mixer flies for Co- Axial copter

Hey everyone,

I’m working on a UAV with a coaxial rotor mounted at the bottom. I’ve used Pixhawk before with existing frameworks in Mission Planner, but now I want to build something custom not sure how to go about this so i came here for guidance

I’m using two rotors, in a coaxial setup, and I’m planning to include a 2 DOF thrust vector control system to direct thrust. Instead of collective pitch like in helicopters, I’ll control thrust by adjusting the motor rotation.

I’m looking for resources and research to help me out. If anyone has custom mixer files or tips, I’d really appreciate your input!
