Ok maybe it's my buzzing at the moment,but Im working on my remote right right now and on my mavics rc PCB main board side.. . On the C1&C2 side ..there is a 3rd button and there is no way to access this button unless remote is totally disassembled and can only be pushed with out outer plastic case...but Sofar, if I push the button I can start remote and shut it off I haven't done much else yet anyone have any info on this curious about this? It's going to dig up sum antenna wires so I can keep it running and screw around with it for a bit I figure anything out about it and I'll post...
