I think Siclick is confusing the 2.4 and earlier 35/36/72 Mhz receivers. The ribbon on 2.4 receivers and switches is built- in unlike the earlier DRs which plug into the receiver. You can buy this ribbon cable at any electronics store, cuts with scissors, red trace polarises it.
Remove the Rx cover and take a look, as far as I can remember it is NOT soldered in but clamped. I think its the same for the switch. It MAY be afactory job tho ! DG
