I am experiencing radio interference with my aircraft. I have a Byron (Fuji) 50 with CDI ignition. Futaba super 7 PPM. When I get 120 feet or so away with the antenna collapsed, I get throttle variation and minor control surface flutter. I have replaced the throttle cable with a nyrod, no improvement. My throttle servo is ten inches from the coil, everything else is 16 inches or so away. Suggestions??
