Abstract:
A steering control device suitable for a radio-controlled model helicopter, comprising:a receiver for receiving three steering signals serially transmitted from a transmitter and demodulating the signals, and then outputting three servo control signals, said three steering signals including a roll steering signal, a pitch steering signal, and a collective pitch steering signal, said three servo control signals including a roll servo control signal, a pitch servo control signal, and a collective pitch servo control signal; a controller for mixing as manipulation signals for three axes of rotation, said three servo control signals output from said receiver and then outputting three servo drive signals for the three axes of rotation, said three servo drive signals including a roll servo drive signal, a pitch servo drive signal and a collective pitch servo drive signal; a synchronous circuit for synchronizing said three servo drive signals output from said controller and outputting said three servo drive signals in parallel; and a roll servo mechanism, a pitch servo mechanism, and a collective pitch servo mechanism, which are controllably driven respectively by said three servo drive signals.
