Default FrSky Receiver advice

I use my old Taranis X9D transmitter from 2013 with ACCST
( NO external module )
2016 i updated the FW to 2.1.9
I have 10 planes with D and X series receivers on D8 and D16 mode
I am very happy with this system, it goes like a train

In all my small planes i have the small and ligth 3,5grams V8R4-II receiver
I need one more, but this receiver is out of stock everywhere

I also have a older ? V8R4 receiver, but that dont work to my system ! ?

I want advice on a small and ligth 4 channel servo output receiver that works ok for my old ACCST X9D

Take a look at the RX4R. Appears to be a current version that would replace the old V8R4. And it is only 2.4 grams!
It supports both ACCST and ACCESS, and also can support redundancy, if that even matters.

You might have to flash it to match whatever version of ACCST you are using. (1 or 2.x), but that's true of all current Frsky ACCST receivers.

Just to recap:
A very, very rare 'bug' was found in the original ACCST firmware (1.0) Most have flow for many years and it never happened. Frsky issued an update for their transmitter modules AND their receivers. It is not backwards compatible - so if you update the transmitter, you have to update all your receivers, or they will not bind. And vice versa: 2.x firmware on the receiver will not bind if ver 1 is on the TX.
This means on new receivers, you have to make sure 1) whether EU or non-EU (FCC) and 2) whether ver 1 or ver 2.x There is no way to see beforehand what is on the receiver, it will either bind, or it won't.
This is completely different than the version of OpenTX you may be running, which does not have to be changed.
The update can be done on even the oldest x9d's. See the frsky site for the updates and how-to-flash things if you need to.

Thanks !
I buy a new RX4R in EU version and hope it works
If not, i try to flash it

2016 I updated my Open TX to 2.1.9

Is there any good info on FrSky / Open TX for dummies somewhere ?
That is easy to understand

This is the most highly recommended: https://alofthobbies.com/taranis-plus-user-manual.html
You may want to contact Aloft, and see if they know of a EU source for it. Actually written by an Australian.

There is also:
Open TX University - but it hasn't been very well maintained, so may be a bit buggy.
RC DIY Open TX - which has a surprising amount of information
PDF downloadable manual
