Radiomaster tx16s mk2 max

Purchased this Radio (450.00 nzd) for both, drones and the J Class yacht on my other listing, I purchased this as well as a ranger elrs module (191.00 nzd), as seen in picture, so this is 4 in 1 and ELRS I'm told this ELRS module can be back end programmed to 2Watts of power for extreme range. comes with Lipos. this has never been used. also a 5 channel ELRS reciever included (elr5ci elrs) again never used. (39.99) I would like to see $500 back on this full set, ill throw in the lipos to power it too. about 700.00 nzd worth.
