Hi again,
I manage to find and fix the issue. Bad contact between interface conector and Futaba. I talk with one guy from technical dept from rc store and he told me I can open the futaba in order to fix this contact without losing the warranty(obviously just to clean the pins) . Also he told me sometime its happening...wasnt first time.
Right now the contact its alright and I can use my rc.
Thanks
PS
You are right, but you must to understand us
, not everybody use those devices, and google its for no use. So, the only solution, its to bother you
