Dan,

The ignition module is not in the plane yet. I am just installing stuff. I have two switches and the battery for the ignition is next to the engine and the battery for the radio is back by the servos. This is a big plane.....GP PT17 Stearman. All ignition components will be in front of the firewall except the switch and tach. I am installing a Smart Fly Optical kill switch but the transmitter for that is back by the receiver and the receiver for the kill switch is also forward of the firewall. Any wires from the ignition going to the tach and switch will be shielded by copper tape and grounded to the engine block, other than that all ignition components are together and 12" or more from the receiver and servos.
