Abstract: A system and method for controlling a multi-rotor aircraft that implements the unconventional use of different sized rotors. The different sized rotors than the main rotors tend to generate an unbalanced torque and pitch on the aircraft that effectively decouples the pitch and yaw control from the main rotors. The atypical design tends to lend itself to improved control capabilities and simplified control systems. Additional configurations implement the use of smaller thrust rotors that can be used to generate thrust as well as control yaw and thus counteract any remaining unbalanced torque from the odd auxiliary rotor.
