You won't be able to do an RSSI range test using the range check function on your transmitter because the XM+ doesn't send RSSI (or any other telemetry data) to the transmitter. 

Your XM+ is giving lower fluctuating readings at the beginning while it's near the transmitter (which is normal) and then it goes up to 99. So I believe your XM+ is working fine. The XM+ has an impressive range and one that is generally further than the R-XSR. You aren't going out very far so I wouldn't expect RSSI to drop at that short distance TBH.

If you take a look at my video in the post below, I'm running an XM+ on that. The goal post I go through is 100 metres from my piloting position. You can see that the RSSI fluctuates below 99 now and again but it generally stays at around 99 which is expected with the XM+ at that range. If I was to take it out further then the RSSI would eventually start dropping.

Understood.

I should have still picked up a r-xsr for whoop as well.
I was just worried if the 70ma current requirement of r-xsr would reduce whoop fly time.

Here's a range test of the XM+ that pretty much matches up with what I'm seeing on my XM+. At 100 metres (~0:45 into the video), RSSI is still fluctuating around the high 90's. It's only after about 200 metres where it starts to go down below 90% before finally going into failsafe just before it reaches the 1km mark...



By comparison my R-XSR starts going below 50 RSSI at around 600m which is usually when I decide to turn around and head back to save myself a 600+ metre walk to retrieve a failsafe'd quad.

Unless you need telemetry data to your transmitter, the XM+ is probably the better choice for micro quads.

Today on XM+ I flashed ACCESS and flashed ACCST back successfully.
Thought of posting here in case if any one wonders if it’s possible.

ACCESS on XM+ did not help the issue of rx loss when Tx near Rx.
However I guess, the reduced latency is making the recovery faster (so whoop is not falling from sky).

I used to have the same issue with my XM+ RX's FAILSAFE'ing when the TX was a meter or so way, but then would fly fine out to 500+ meters. I cannot find the video any longer, but someone had done some experimentation and demonstrated close in FS's.

I still have 2 quads with the XM+, my original Lizard95 and a 110mm 2" I built out with the parts from my 2nd Lizard95. I was surprised at how well they handle medium range flying when compared to my R-XSR. In a yard flyer, the XM+ equipped Whoop should be awesome!

ACCESS on XM+ is giving more failsafe than ACCST.

Question on updating firmware/OpenTX for radio.

If I understand correctly, firmware update for the radio is provided by FrSky and we download that from FrSky website and install using the radio.
OpenTX updates, we use OpenTX companion and flash the radio with latest version.
SD card contents, download for the relevant OpenTX vesrion.

• While doing any of the above, will my current setting get lost?
  
• Can I copy and paste new sd card contents to existing SD card and do replace all.?
  
• FrSky website has several firmware for x9 lite, should I just take the latest and flash? Will that have all previous updates?

• While doing any of the above, will my current setting get lost? No, all your models and settings will be retained when you update either the ISRM firmware or OpenTX. However, I always recommend doing a backup anyway just as a belt and braces approach in case something does get corrupted for any reason. Instructions on how to backup up your transmitter settings and models can be found HERE.
  
• Can I copy and paste new sd card contents to existing SD card and do replace all.? My recommendation is that you create a "clean" install of the new card contents by copy the current contents of your SD Card to a backup folder somewhere on your computer, then delete or the files on the SD Card (or reformat it), then copy the new SD Card contents for the version of OpenTX you've installed to the SD Card. If you had any custom LUA scripts of other files then copy them back onto the card from the backup folder you created on your computer earlier.
  
• FrSky website has several firmware for x9 lite, should I just take the latest and flash? Will that have all previous updates? You just need to install the latest firmware version which includes all the enhancements and bug fixes from previous versions.
  

Answered above in red.

Everything worked except that XM+ (ACCESS) binding lost.
So I tried re register and not happened.
Reflashed ACCESS and still did not register.
Finally flashed ACCST back and it got blinded.

Any way I was having more failsafe with ACCESS.

Sorry, can't really help you too much with the ACCESS stuff because I'm still on the proven and working ACCST protocol.

Because ACCESS is still quite new it may just be some teething problems coupled with the fact that they are now running more processor intensive code on the legacy XM+ and R-XSR receivers which are both a good few years old. Maybe the MCU on those receivers is only just on the verge of being able to cope with the amount of processing required for the ACCESS firmware. There will be additional encryption/decryption going on for starters.

Here is what went wrong,

“The XM+ is only supported until ACCESS 1.1.2, so not really supported. 
As your X9 lite is on 1.1.3, they are not compatible, and will never be in the future. 
XM+ is effectively ACCST only.”

Where did that statement come from? Was it from an FrSky representative or someone else?

If it's true then that's another kick in the teeth from FrSky. They promoted the fact that some of their older generation receivers would continue to work with the ACCESS protocol. They didn't say anything about support stopping after a certain firmware version. So they went back on their word.

It seems yet another good reason for people to stay well away from all the ACCESS stuff, unless they are prepared to fully embrace the new FrSky Archer line of receivers which have been specifically designed to support ACCESS. protocol and are not backward compatible with ACCST. But those aren't due for release until at least the middle of January.

It came from few fellow RCGroups members.
However after searching I found the same Frsky XM+ firmware download page too.

“* Compatible with the ACCESS radio if its ISRM module in support of firmware version 1.1.1 or 1.1.2.

Otherwise, please use the ACCST firmware and bind your radio in D16 mode.”

R-Xsr does have 1.1.4 firmware version listed in their website.
