JFC...... Now i am really confused
From what I am aware,
Even when you have a PCM or a Failsafe unit install, A failure on the RX battery will render them unoperational, so the throttle or steering servo will be at the same position before the RX battery failure, meaning, when you pull WOT before the battery failure, your throttle servo will remain WOT and not return to its neutral position or Brake.
Yes you are correct, Failure on the TX battery will make the failsafe kick in.
BTW, the position on the throttle can be adjusted on either the PCM or external Failsafe unit, not neccesary to be in braking position, can be adjusted to neutral.
