This is the version 2.5 firmware released summer 2013
together with the version 7 hardware.
(this version firmware is offcourse also compatible with older RX, and they can all be user upgraded)
Up to 3 different failsafe positions can be saved into the receiver.
The first is stored like usual, push and hold the bind button while in flight mode.
To store the 2nd failsafe, change the sticks positions, flip a switch on the remote as you want, you got 5 sec
from the previous save to pust the bind button again to save the next, and so on.
if you wait over 5 sec, you only store one failsafe.
The serial out of the rx will explain live what happens and what you did.
turn on/off the tx to recall and check settings.
Be aware of one minor detail : the rx will get out of sync while it save the positions, this means it also recall failsafe 1 during a save.
