| The Servos used for remote control model aeroplanes and helicopters are an obvious choice for controlling equipment in high altitude payloads (such as camera control and steerable recovery systems). | The Servos used for remote control model aeroplanes and helicopters are an obvious choice for controlling equipment in high altitude payloads (such as camera control and steerable recovery systems). | ||

| The control signal takes the form of a pulse train – nominally with a period of 20ms – but anything in the range of 18 to 25ms should be expected to work. The pulse length is varied to set the position of the servo – 1ms equates to a position at one end of travel – 2ms to the other end of travel – with 1.5ms being a central position. | The control signal takes the form of a pulse train – nominally with a period of 20ms – but anything in the range of 18 to 25ms should be expected to work.
