Building my first gas GS Warbird and have no experience with gassers. I have been told that the kill switch must be installed forward of the firewall or else it will cause interference with the radio. Is this true? Because of the contour of the bottom of the cowl and fuselage there is not an inconspicuous place to put the switch unless I place it behind the firewall. What about the throttle servo, can it be placed forward of the firewall?
