Remote control device

Abstract

A remote control device includes an instruction transmitter and a controller which controls a speed of an unmanned helicopter based on an instruction from the instruction transmitter. The instruction transmitter selectively outputs one of a speed change signal that changes the speed of the unmanned helicopter and a speed determination signal that determines the speed of the unmanned helicopter. When an output from the instruction transmitter is changed from the speed change signal to the speed determination signal, the controller determines whether the speed of the unmanned helicopter should be maintained or brought to zero based on a result of comparison between speed information of the unmanned helicopter and a threshold value. Preferably, the speed change signal changes the speed of the unmanned helicopter by changing a tilt angle of a nose of the unmanned helicopter in an up-down direction in accordance with an amount of operation applied to the instruction transmitter.
