I tried to connect Phoenix simulator to my Tx-Futaba 4EX. It was showing connected but not responding to stick movements.
I opened the case and saw that three of the connecting wires have lost connections. (Pic attached)
The wires are marked as A, B & C with corresponding probable connections as A, B & C.
The wire A seems to some kind of earthing connection. The three connections on board are -
A-GND2
B-OUT
C-VCC
I loosely connected them and could see the Tx work.
I am planning to solder these connections.
Am I moving in the right direction? Can someone help me confirm?
Does anybody has the circuit drawing of this Tx.
Did the soldering.....working now.... ;D
