<p>A servo circuit board structure for a remote control model helicopter is to solve the technical problems of reducing the overall volume and lowering the production cost. The servo circuit board structure for a remote control model helicopter comprises a frame (12), a motor (28) disposed inside a servo fixation base (31) on the frame (12), a screw rod (29) and a sliding block (30) for connecting the thread of the screw rod (29). The upper end of the servo fixation base (31) is connected and fixed with a main control board (4). A first servo circuit board (5), a second servo circuit board (6), and a third servo circuit board (7) are inserted on the main control board (4), The first servo circuit board (5), the second servo circuit board (6), and the third servo circuit board (7) are connected and fixed inside the servo fixation base (31) respectively. Compared with the prior art, by adopting the manner of directly welding the pins of the main control board and the servo circuit board together, the mixed control function of the servo is implemented, the structure becomes more compact, the volume is smaller, and the production cost is lower.</p> |
