@MikeR Does your commando 8 have an orq ghost transmitter module connected to it? If it doesn't then it is likely using ELRS which is not compatible with a ghost receiver.
You'd need a orqa transmitter like this one: https://shop.orqafpv.com/products/orqa-orqa-fpv-ctrl-radio-controller
Maybe your other drone had an ELRS receiver on it?
