Hello  after doing my two Bachmann K-27 i also want to do the same with my two articulated engines.  i am going to use the new Phoenix SM18 and a CVP Airwire converter 60 to power the two engines. what i would like to know can i use the Bacmann main board to hook the battery to the converter 60 then the DC18 Input to replace to wheel power pickup.  if that would work then all one has to do is switch over to battery power on the main mother board.  at the same end of the mother board is a DC6 Volt input to activate the chuff sensor.  both are screw on mounts.  right now i am batterey powering my two accucraft C-19 which i had long before Bachmann came out with their.  thank you for any input good night   James S
