Yes, they use the same case and the battery port (which can be any slot) is also channel 8.

I am confused about Futaba receivers. I have a 7 channel R127DF and an 8 channel R148DF. They both look the same to me. That is they have 7 servo slots and a battery slot. On the 148 it says 8/B, and I don't understand that. Can anyone help?
Thanks,
Richard
