I posted a reply to a question on this matter on another group and thought I'd re-share here.
Hallo everyone,
Ok here's the skinny. Some of the Spektrum recievers, yes only some of them not all of them but mostly the newer ones, actually have two forms of failsafe. This works exactly the same as your good ol PCM failsafes works where you can select a preset position for each servo to go to should the reciever go into failsafe OR the reciever can remember your last input on the transmitter right where the lockout occured. On my old PCM setups I used to preset the throttle to go to idle always and the rest of the controls to remember last input.
Now on the Spektrum stuff you have no choice regarding throttle, it will always go on to idle along with it's few other gadgets to help safety on electrics. But you can still choose if the other controls should go to a preset or remember last input. Here's how it works long and short.
Put the bind plug into it's respective plug/socket whatever, switch on the RX power and now the reciever is in bind mode (Flashing lights, very pretty!). Should you need to adjust any failsafe settings or anything plugging in the bind blug will ALWAYS reset the reciever so you can "re-bind" and make minor adjustments. So for the first time get the reciever to boot, now hold in the bind button on the back of the TX and power on the transmitter. Hold the bind plug untill all the lights go solid and then you can let go. Now you can remove the bind plug on the recievers side. Now it's time to adjust everything and make sure everything is working like it should in the right directions and and. If you want to set the failsafe to go to preset positions you set the trims now for this on all the surfaces including the throttle to go to idle. (Power down). Now put in the bind plug again, do the rebind and now do not move ANY of the sticks whatsoever once it's binded, simply release the bind button on the TX and remove the bind plug from the model. Switch off the RX, switch of the TX and viola everything is programmed to go to preset positions... Test it by powering back up, moving things to odd positions and switching off the TX to see if the surfaces moves to where you told them to.
Now to set the reciever up to hold last inputs apart from throttle going to idle do the whole bind process BUT as soon as everything is binded simply let go of the bind button on the transmitter and wiggle the sticks. Make sure the idle was in the right place when you powered up though. Once you wiggled the sticks you put it into Smartsafe or whatever they call it and all the surfaces will now remember your last input apart from throttle. Now remove bind plug on RX and power down on everything. Power back up and test it by for instance moving throttle to full (to check that it moves it to idle) and hold the sticks in funny positions while powering down the transmitter. All the surfaces should hold that last input except throttle.
Done.
