A coaxial dual-rotor model helicopter system includes a power control mechanism, a transmission mechanism, a control mechanism and a rotor mechanism. The rotor mechanism includes an upper rotor (12) and a lower rotor (22) coaxially installed on an upper side and a lower side of a main shaft (8) and controlled by an inner shaft (81) and an outer shaft (82) for rotating. The control mechanism includes a Bell self-balance mechanism (11) to control the upper rotor (12) and a Bell-Hiller control structure (21) to control the lower rotor (22) . The power control mechanism (3) controls the rotor mechanism through the transmission mechanism and the control mechanism. Thepresent invention achieves balance effect through the upper rotor (12) by employing the Bell self-balance mechanism (11) that has a great stability to provide automatic control. The lower rotor (22) aims to control direction and employs the Bell-Hiller control structure (21) that has a high maneuverability to perform active control. |
