Hi, I have been a dedicate fan for Arducopter and Arduheli for quite sometimes, love and appreciate all the effort that was pouring into them.
I am now researching on the Coaxial Helicopter like the Ascend Aerosystems’s Sprite and wish you develop my own smaller version for small payload and long endurance setup.
So far, I found that PX4 has support for Coaxial Helicopter with such configuration. but I believe that the only difference in the control would be the yaw control; which instead of using tail rotor, difference in RPM of two main rotors are used for yaw control. Are there any mixing option in Arducopter or Arduheli to achieve such a control? Is there any custom code available for such a configuration?
Any suggestion is appreciated.
