GEOHARRY, your not the first and wont be the last person to state c+g doesn't effect hovering performance because you have gone PAST the stall !. Quite right but you all forget what about getting into the hover, getting out of the hover and combing manourvers before and after the hover ???? All of which would be very difficult with a forward c+g and blooming dangerous with too far an aft c+g. Needless to say the c+g is critical for whatever you want to do - for 3D it wants to be aft but not so the plane becomes a real handfull in normal flight - PERIOD.
