Title:
ROTOR CONTROL DEVICE OF R/C HELICOPTER
Document Type and Number:
Japanese Patent JP3958747
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotor control device of an R/C helicopter to control the pitch angle of the R/C helicopter by the SWM system capable of stabilizing the flight posture by mixing the output signal of a gyro device with the control signal of a servo, improving the steering responsiveness of a tandem rotor, and realizing rapid, reliable and easy steering.
SOLUTION: A gyro device and a mixing device of SWM system are provided on a helicopter body. The mixing device comprises a demodulation unit to demodulate each pulse-width modulated steering signal of a pitch, an aileron, an elevator and a rudder to be output from a receiver, an operation unit which mixes each steering signal to be output from the modulation unit with each posture control signal of the aileron, the elevator and the rudder to be output from the gyro device to generate the control signal of each servo device, and an output unit which adjusts the control signal output from the operation unit and outputs the driving signal of each servo device. The mixing device mixes each steering signal transmitted from a transmitter with each posture control signal of the gyro device, and operates a swash plate of front and rear rotors by the SWM system.
