OTHER: Electrical - Control - Contactor:

Notes on Main Contactor (Solenoid):

• I suspect that a resistor, of sufficient amperage, should be located in series with the coil so that the voltage through the coil is within the Maximum PULL-UP and Maximum DROP-OUT voltages recommended by the manufacturer. I.e. there is no reason to have the coil voltage as high as the voltage through the contacts.
• Motor Control Contactor.
• Consider using one contactor for both the starboard and the port control circuits. This is because if one motor quits driving then they both must quit driving.
• For DC current.
• Coil type: Continuous, Intermittent and Latching. I believe that the helicopter will be considered continuous.
