Sorry for my ignorance on this subject, but I am confused as to where
to mount a ground plane for a carbon aircraft. I am building a
Lancair Legacy RG - carbon and want to integrate a copper foil radial
ground plane into my com antenna setup. It seems like some have put
this inside the aircraft, where others that use the metal "spray"
paint put it on the outside. Does it matter? I basically do not have
a good concept of how a ground pllane is supposed to work. ( I have
read the aeroelectric connection - still confused.)

Thanks

Use the copper strips inside the fuselage. Metal sprays
are absolutely inadequate to this task whether inside or
outside the airplane. Been there, done that, sprayed on
(even flame sprayed) coatings are NOT a substitute for
a contiguous pure metal conductor.
