those batt backer toys might not have a common ground. Have u asked the manufacturer? I think I will call tham Monday.....thanks for the link.
as far as I know, the ElectroDynamics is the only backer that eliminated the common ground....the Smartfly does not ( I use them) ....even the $800 Powerbox Royal does not break the common ground.....let us know if the 42% backer fixes this...I bet it doesn't....
