Urgent firmware update to all X receivers and RF modules (ACCST D16) just released

Thank you Mike!
I'll see if he wants to try that method.
Personally, once he updates OTx from 2.0.17, I don't see any reason to go back to 2.0.17 after the XJT has been updated.

The problem, as I understand it, is his models won't update from 2.0.17 to 2.3 in one step. They have to be updated first to 2.1, then to 2.2 and finally to 2.3. I'm not sure whether they update on the radio or need the corresponding versions of companion to do the updates.
If he is happy to re-enter all his models, then yes, just go to 2.3, otherwise, he might prefer to follow my suggestion and stay with 2.0.17.

Very good advice!

You MUST be on the same version of ACCST for both the receiver and the transmitter. Current release is 2.1, but FrSky does not yet have it for all products, so best to hold a bit longer.

If you must try it, here are some instructions Lothar put together to help folks out! Just select the version for the transmitter type you have.

I'd suggest doing the binding again -- and testing in your shop with the Jug

Yes I agree with Scott. There are documented cases where re binding was not done resulting in poor range performance. One tell tail effect is to view the green LED on the receiver and see if its on solid or blinking occasionally. Blinking means its not a solid bind. Definitely re bind the receiver.

So, to be clear, the original instructions from Lothar, which Wayne posted, were incomplete. There was no mention of re-binding, even though this is a critical step that if missed can lead to a crash.

A year and a half after the loss of my 104" Extra 300 someone on RCGroups posted an explanation for why I was able to get over 200 flights on that plane without ever re-binding:

I had been flying at an airfield where we all take turns to fly - one at a time. It was at the club fun-fly, in a crowded frequency environment, with multiple planes in the air at once including mine, that the missing step finally caught up to me.

In 2020, after I upgraded the firmware in my X9D+ and in all of my receivers to ACCST v2.1, they worked without re-binding and each passed a range test. I was not aware that re-binding was a necessary part of the upgrade process. I attribute the total loss of my Extra, a $5k investment, to this missed step. I'm really disappointed that Aloft passed on incomplete information. I came here expecting to find the most accurate documentation on the upgrade. Seems like FrSky left everyone groping in the dark.
