No i have no experiement running, the Relay satelite have only vanilla part and the HECS core, the small HG-5 antenna and that small foldable solar panel.
Tried to recreate it in the VAB without the Antenna and it still show the consuption at 12EC.
Also noticed that most of my mods may be non fonctional.... what version of module manager do we currently need for 3.0?
