Im new to gas and ignition setup so this is what I understand so far,

You can have reciever ,batt. and plane servos on one switch, then ignition and batt. on another switch not tied to reciever.

But what if you have the switch for ignition in the retract gear of RX and two batts. combined with a switch that has 6v regulator (seen in one of my magazines) on the other end. Then would you be able to cut the power to ignition, which will cut motor?
