[TowerTalk] Switching Multiple Rotors

You can use one wire for switching and the rest for control, IF you  
have enough wires in the cable.  Obviously, you need a common ground,  

The switching can be used for up to 4 rotors, if you use:

1 - no voltage
2 - +12 v
3 - -12 v
4 - 12v ac

The voltage can be whatever will drive your relay set.  I simply put  
12 volts as a reference.

Use two DPDT relays ... with diodes to select which is 'thrown' (and  
electrolytic capacitors to keep them from chattering on AC).

Appropriate bypass capacitors (and RF chokes, if needed, complete the project.

Good luck,
