My main Tx that I expect to use to get flying again after a big break is a Futaba 7UAPS, and once I get some degree of competence/confidence back I'd like to get a buddy arrangement to let my son have a go too.
Does anybody out there know if I'll need to track down another 7U Tx to buddy with, or will any other Futaba(or other brand) Txs buddy with it? If I need another 7U then it may well be easier to buy a couple of Turnigy 9xs and leave the 7U in retirement.
Thanks.
