Thanks f5soh .
I'll buy a couple 12v to 5v regulators, ( dist. boards ) . If I have to do any filtering I'll use the 3.7v contact point described in the Spektrum DSM2/DSMX set-up pages in the Wiki. I won't be using a satellite receiver , just a XY7000S only , so I hope I can just plug in and configure .
