CONTROL DEVICE OF REMOTE CONTROL HELICOPTER

摘要

A control device of a remote control helicopter comprises a rectangular frame (4). A main motor (2) is disposed in the frame (4). An output shaft of the main motor (2) is connected to a driving gear (3). A driven gear (10) engaged with the driving gear (3) is connected to a main shaft (9). A main steering engine mechanism (7) is disposed at the rear end of the frame (4). The main steering engine mechanism (7) is connected to a pull rod mechanism and a swashplate mechanism of the remote control helicopter. A tail steering engine mechanism (8) is clamped at the rear portion of the main steering engine mechanism (7). The tail steering engine mechanism (8) drives a tail fin pull rod mechanism, and meanwhile drives a tail fin to rotate through the driven gear (10). A printed circuit board (1) being connected to and controlling the main steering engine mechanism (7) and the tail steering engine mechanism (8) is disposed at the upper end of the main steering engine mechanism (7). The size of the control device is reduced, and the control device can replace or adjust a tail transmission mechanism fast.
