He said his servos were new. The 'KEY" here is that he has a Fuji engine. For some moronic reason, Fuji has seen fit to NOT supply thier engines with shielded spark plug wire or metal cap. I have the same engine and the same glitching. The only thing that got it under control was to take some shielding from coax cable and put it over the wire and cap and then solder a wire to it and ground it to the engine. It is very frustrating to have such problems and Fuji does nothing but say 'send in your engine and we'll look at it'. Why they don't retrofit the engines with shielding is beyond me.
