Hey guys I am setting up my first gasser and i have a few questions...

My radio Equpment is a Futaba 7c with the Futaba 617fs...

OK I do not want to have to use a y harness or my alerions or my elevator... so i need some help also i want to run dual batts just for saftey.... also i will have a chock servo and a opto kill switch.... now my problem is on my reciever it only has 7 ports so that is 6 channels and then channel 7 is shared for the batter so how do i hook this thing up with out having to use y harnesses..... right now i have two recivers in the plane but its only because i can not figure out how to do it on one

there is
a servo on each wing so channel 1 and 6
a servo on each elevator so channel 2 and 5
1 rudder servo channel 4
1 throttle servo channel 3
channel 7 for choke servo so now i have ran out of space and i still need a spot for my batts and my opto kill switch
any ideas will help thanks all
