The coreless servo reduces the possibility of harmonic feedback caused by vibration. Many years of pylon racing has taught me this.
A regular servo will generate electronic static from engine vibration or even control surface flutter. Don't believe it? Ask around the
local pylon racing gang. Vibration is a source of electronic static hell.
The 2.4 GHz radios have all but eliminated most of the RF interference issues but why not continue good practices even with
current new technology. If you are getting a anomaly then all these old practices can do nothing but help or be useful in the
process of elimination.
Rest assured, if I DO start getting RF problems I will shield the plug wires and caps. Maybe I am just lucky but I have not had a serious RF problem flying gas/ignition with the outdated FM PCM ( which I have discarded all ) or the new 2.4 Ghz systems.
