I got the receiver out of the helicopter
And it should work but the cables i use from the control board to the receiver do i get them with the control board or do i have to order them?
The transmitter should work as long as your receiver talks the same frequency and the same protocol(s). I'm not sure about the board you got, but most boards come with the cables. I don't see why that one wouldn't.
Usually, min. numbers of the channels to control quad is 6 just for basic functionality, implemented in Flight Controller. More channels, better service.
