I am new to this community, seeking some help in finding the right flight controller. I am building a custom 700 size twin rotor (tri-blade) co-axial helicopter. This heli has total 2 swash plates for 2 rotors and each swash plate have 3 servos. Currently I am in phase of interfacing the flight controller for my custom heli. I found Pixhawk 2.1 as most suitable flight controller but I am not sure if this flight controller has readily available option/program to control co-axial helicopter? could anyone please guide me on pixhawk 2.1 or 3.0 options?
Thanks in advance,
