I am new to gas and need some advice on set up. First of all I am flying a DP Extra with a Fox 2.4. Range test with the engine off is good. Range test with the engine running and antenna down is very poor (10 feet). Range test with the engine running and antenna extended is good. Here is my set up .... the receiver antenna is running down the inside of the fuse in a plastic tube and exits just above the right elevator servo. Is this a problem? My throttle linkage is nyrod but my throttle servo is mounted on the right side of the fuse just one inch above the receiver. Is this problem? The only other metal in the plane would be the pull-pull set on the rudder but that seems to be normal on many planes. My switches are separated by 8 to 10 inches. My ignition battery is on the fire wall and the plane battery is inside the fuse ... separated by 10 - 12 inches. Any suggestions would be appreciated.
