I have a XYZ 26cc on EI and The install puts the ignition module on the outside on the the firewall. The battery is located inside but is forward of the receiver by 9-10 inches. The only thing that even comes close to the ignition battery is the throttle servo. The throttle linkage is non-conductive save for the metal threaded ends on the ny-rod. With this installation I should not get any interefernce but when I crank up I am okay at idle but anything above idle the throttle servo starts glitching. The control surfaces are not affected and operate normally. I have changed out the throttle servo but still get the same results. The sparkplug is a NGK CM6 and is a resistor plug. The plug wire comes shielded and is not touching anything else metal going up to the plug. I've thought about relocating the throttle servo further back in the fuse, or shielding the ignition battery and wires with wrap-around shileding but don't have a clue if that will work. Any suggestions would greatly be appreciated.

Happy Flying!
