Sorry, I missed that earlier. I didn't realize you were using a 5e, so you don't have a file capability.

What happens in normal operation when you pull the trainer switch? You said it changes the position of the throttle servo when you're binding.

Also, try releasing the switch shortly after tx powering up, not waiting until the end.

Perhaps you have found a problem

Try an older DSM2 only, Rx
and see if Failsafe works correctly.

I really think the problem is related to what he reported at Step 8. The throttle changes position from high-throttle to stick position when he releases the trainer switch.

Andy:

Could you elaborate a bit on when to release the bind button/switch, please.

My understanding was that you only need to hold for a short time and that holding it for the whole process can interfere with binding.

I know the first part is correct, as I always release as soon as the receiver shows a response and stops flashing. Not sure about the second part, but I notice that you pick it up as a possible issue in this case.

Confusing indeed. a different Tx would indicate nothing wrong with your original Tx
Have you an older Rx to try ?

Otherwise as said by Andy
We are all missing something here

WHEN ALL ELSE FAILS READ THE MANUAL.
Page 10 of the DX5e manual states "Continuing to hold the trainer switch during
the binding process will prevent the preset smartsafe
position from being learned by the receiver"

page 11 of DX4e manual states CAUTION: "Continuing to hold the trainer button during the binding
process prevents preset failsafe positions from being learned by the receiver."

Since this particular plane requires the throttle servo to be reversed due to layout of servos and linkages, the reciever appears to be reverting to default failsafe (ie throttle servo not reversed)

I am not with the plane right now but will check this evening. I am sure that this is the problem, not releasing trainer switch in time. This was driving me crazy I was specifically using DX5e and verifying with DX4e transmitters because they are pretty simple with no chances of erroneous programming settings. Thanks for all of your time and effort to straighten this out Andy even though it appears that this was probably pilot error. After I verify that the rx is working properly I will post a final confirmation.

Spektrum/Horizon Hobby customer support is second to none!

lol. glad you seem to be sorted

No problem with equipment, all DSMX. Appears to be the problem of "who needs instructions".

Or same pilot error with multiple pieces of properly working equipment.

Re-bound, letting go of bind switch as soon as tx lights flashed. All is working good.

NOTE TO SELF let go of bind switch after power up.

NOTE TO SPEKTRUM Since this lack of failsafe, only if throttle servo is reversed, is not evident as every other function works and rx indicates bind was successful you may want to consider when updating software including a setting that will not allow the bind to happen if switch is held up.

The switch is used at the start to enter bind mode, not the end.

My own procedure - is to enter bind -holding switch/button etc., till i see a reading on the screen (on screen equipped radios) noting the bind is complete.
On non screen models of tx - I just watch the rx till the flash stops then let go the switch.
which or what other visual aid do you think is best?

You can let go as soon as the tx enters bind mode. The first beeping or the bind screen showing.
