Even IF you have a system like the NAUTICAL COMMANDER with the seven channels on it, there may come a time when even this system just is not enough. So what are you to do? One answer is simple, just add a switch. This is a simple electronic device sold by several companies that plugs into one of your channels. MCD for example, offers a switch that installs between the receiver and one of the servos or a speed control and can independently control 2 on/off functions. The control stick, in its normal range, controls the servo or speed control in the normal manner. If the stick is moved rapidly to either end of travel, the circuitry in the ADD-A-SWITCH remembers the last setting and maintains it. Then moving the trim in the corresponding direction, the switch function is activated.
If you need more than 2 on/off functions, then MCD has an answer for that also. The SWITCH 8 Accessory Control System is designed to control up to 8 on/off functions from one channel of the radio system. The unit consists of 2 parts; the decoder section which is installed in the model, and the eight-button keypad which mounts on the transmitter.
The SWITCH 16 Accessory Control System is designed to control up to 16 on/off functions from just one channel of the radio system.
