Very very true John_M! ...And actually if one have soldering capabilities I would strongly recommend to avoid all those Futaba Hubs and extension cables as those just introduce additional connectors: ie potential point of failures. I prefer to implement whole wire harness custom to every plane and then you can choose the best cables and connectors too. Anyway fixing everything well is key regardless of the method used. And especially if you go my method then it's critical to support and fix the wires well to avoid fractures next to solder joints. And with SBUS you can allocate the another R7008SB to your other plane - with SBUS you can use all channels with one receiver.
