Phil, John..
I believe that the Futaba FP-T6NH is the same as the
FP-T5NH, with minor changes to make it a 6 Ch Radio.
I have Managed to get hold of a scope and figure out the pinouts for a Futaba FP-T5NH and make an interface that works prfectly!!
I reqiures a bit of soldering and I am currently doing some photos & diagrams to show how its made.
If anybody needs to know how its done please email me..
