Selling my collection of FR sky receivers I no longer use since going to ELRS for FPV and Futaba on the larger stuff.

Buy the lot all 12 for $200 and get free postage anywhere in Australia less than $20 each can't go wrong.
The Black TFR8S you can link together to make a 14 channel rx with 4 aerial reliability.
The Blue Delta 8 you can use as a wireless buddy box system it works great just bind the trainer to the rx and plug the rx into you master tx, beats having a cord.
I think all work with Futaba. I have used them in petrol planes, drones, gliders, petrol helis and nitro and electric jets and all work great without any issues.
