Coaxial Drone Configuration (Fixed-Pitch Upper, Variable-Pitch Lower)

Hello community,

I’m in the process of building a coaxial drone and am seeking some advice on Firmware Selection & configure to handle my specific setup. is there any specific firmware or frame type is available for the variable pitch coaxial drone.

My drone design consists of two rotors: the top rotor is 1 fixed-pitch, and the lower rotor has variable-pitch blades. I want to ensure that I use the correct firmware and frame type for my build.

Here are the key details of my setup:

  1. Top Rotor:** Fixed-pitch propeller.
  2. Bottom Rotor:** Variable-pitch propeller, which I intend to control for adjusting thrust.
  3. Frame Type:** Coaxial (with one rotor above the other, aligned along the same axis).

I’ve come across some general coaxial drone projects (such as the T-Drone open-source build) and found that they often use custom settings, so I’m open to suggestions on how to modify ArduPilot to fit this design.

Any insights or suggestions would be greatly appreciated. Thank you!
