Hello, I'm just wondering if trainer cords on transmitters can be used between brands. I am thinking of buying a Futaba 6EXA 6-Channel FM, but I heard that the trainer port is of a new design and will not work with older radios. Is this true? Would a JR XP6102 6 Channel FM Radio be compatible with all the major brands (especially Futaba because most of the flyers at my field use Futaba)?

On a slighty different note, which radio I mentioned above would you consider to be better/ more worth the money?

Thanks for your time.
