Thanks Luke. Any other receivers that would work with the old firmware radio? I can return this and get another. Hard time finding an xr4 anymore.
If nothing out there will have to do as you suggest

You mean thanks "Jürgen"!

Here are a couple threads I found on RCGroups about the same issue that Jürgen has mentioned: 
Taranis QX7 / X8R wont bind. Help!
Qx7 & X8R not binding - both international version

I have not kept up with all the developments in radios and receivers the last many years, so I don't have any recommendations to give you. I'm sure there are many options, but as usual, Google is your friend.

Things have certainly got a lot more complicated from the old days when you just had to have a matching crystal. For model tanks all this extra complexity is overkill, but I guess it's the only option nowadays.

Thanks Jurgen! I may try to grab a x4r at some point if I can find one. If anybody knows of a receiver that will pair with this older firmware Taranis Q7 let me know:)

All compatible receivers will have v2 firmware....
Simply download the old v1 firmware for the receiver from Frsky, flash it, and you'll have a compatible one.
Anyone who is able to configure a TCB should also be able to flash a receiver. 
There is no other way.

Thanks. Seems like I need a few types of connector cables for the receiver but that seems easy enough.
The downloads to the proper one for x8R for taranis Q7 1.0 firmware. Is there a best link to the best/proper one? I didn't find it on the frysky
site..again maybe missing something lol. I did see other sites though. It isn't a rush just curious and thank you for the help/advice!

I noticed the track recoil triggers exactly with sound and flash but before the barrel itself recoils which looks a bit odd as if the tank did kick
back a bit it would be when the barrel recoils back into the turret. An adjustable delay would be cool to allow the barrel to recoil back.. then the tracks would
trigger. Also, the new effect when hit with IR would be more realistic as the round would have a delay before it hit another tank at range. Just a thought

[Tom]

Thank you!!

Have a few Benedini Mini's that work. They don't make them now my old DasMikro used to connect to use but not anymore. I think they used the older
versions of for Flashing/connection which won't connect now. Do the current DasMikro work with Flash V4?

Hi Tom,

If you have any trouble getting your X8R downgraded to the v1 firmware, please feel free to reach out to me.

I work for FrSky in the US office, you can find me on Facebook also under "FrSky Ben", or feel free to message me directly here.

As others have mentioned, your radio is likely on older v1 firmware, and any receivers you buy new will be shipping on V2 firmware.

Be sure to flash your X8R with the "FCC" version since you are in USA you are likely on FCC version radio also.

And yes, X4R have been discontinued for a long time, so pretty much only way to find them would be second-hand market.

Lastly, if you buy any of the newer 'ARCHER Plus' receivers, they -will- work with your radio, but they only support v2 firmware, so you'd have to update your radio to v2 as well as all your older\existing receivers that you have (and rebind them)

Just let me know if you need any extra help with it.

[Tom]

Thank you!!!

Hi Tom, if the track recoil/sound/and flash do not occur when the barrel recoils, then you can synchronize them using the option dedicated for that purpose in OP Config: "Delay between recoil and light/sound" on the Motors tab, under the Mechanical Barrel heading.

This will not change the track recoil when receiving an IR hit, which will continue to occur the moment the hit is received. I am not inclined to add a delay to that one.

[LukeZ]

Hi Tom, I'm afraid I don't know the answer to that question, as I have not personally used the DasMikro boards. I can only suggest that you will have to try one to see.

[Tom]

Flash, recoil, sound and track kick back all sync. Just thought a slight delay option on track kick back could allow it to happen when the barrel slams back to the turret.
Just seems it might add a bit of realism.
But just a thought:)

[Tom]

Will do and let you know. I hate though the clones killed the tbs for Thomas. I would buy his if he was still able to make them..
