Having left the update path well alone for three years and happily bumbled along on 2.2.4 I decided to bite the bullet and update to 2.3. I started with backing up all existing files and then downloading Companion 2.3.7 to my MacBook, got the radio settings in and went for the "download firmware". At this point I got a "Unable to save the file: read-only file system". I thought I might be able to work around this by getting the firmware direct from OpenTx but it can only be acquired through Companion, so I'm stumped. Anyone know what the problem is (I suspect it is the Mac OS) and, more hopefully, what a solution might be? Or should I just buy an X20 with Ethos??!

Bingo! I updated the internal module firmware as supplied by Matt and instant result. Thanks to all who have chipped in, another hard won lesson learnt - I didn't know about the need for updating the XJT module. I guess now I will have to move on to updating my other receivers (one of which is D8, will that still work) and look forward to flying rather than fiddling with radios!

Thank you Matt for your detailed explanation, I will go through all of the steps outlined and report back. As regards the issues outlined in my previous post I have resolved them by deleting OpenTx on my Mac and re-installing, I then downloaded the appropriate firmware (same as in your zip file).

As I feared I am running in to issues trying to update firmware. The files Matty supplied I cannot select, they are ghosted out, so I go to OpenTx website and select the firmware from there. Using Companion I select the download button and I get this: So I then select "yes" because of course I want the firmware, but get this: So I'm at a loss as to how to proceed .................

Denis, I have followed the exact procedure you refer to in the attached "manual". At part 2 I am not getting the red flashing LED. I've just had another couple of attempts just to see if for some reason it wasn't "sticking" but to no avail. I can only assume that the Rx is faulty.

Steve, that was just an initial typo on my part. On every occasion I have flashed with RX6R_LBT180516.frk. Still not working ..........

Ok, tried the RX6R_LBT180516.frk flash yet again but still no joy. No flashing red just permanent red/green after binding. Maybe the Rx is faulty?

That's the firmware I first tried before this morning's attempt. I'll flash it again to see if it takes.

I wish to stay on ACCST so 2.2.4 is as far as I need to go, mine is also the original version of ACCST. I recently bought an X8R from T9 which came with the later version of ACCST so I flashed the Rx back to earlier version using the file X8R_LBT_180322.frk and had no issue binding.

Not sure what you mean Steve, I can see our Tx are on different versions or can you see something amiss on mine??

This is all the info I can find: Does this tell us anything or do I need to look elsewhere??

On my Tx radio setup page 5/9 is "Version", it tells me VERS 2.2.4 which matches my Companion software. As I understand it the latest receivers are shipped with a newer version of ACCST which is not compatible with 2.2.4 hence the need to flash to an earlier version. Or have I misunderstood? I flashed RX6R _ACCST_2.1.1_LBT.frk this morning and still no bind.

Thank's for the reply Andy. No, it is RX6R receiver I have. How do I check which firmware version I have on my Taranis?

Despite repeated attempts I just cannot get the RX6R to bind, purchased in 2020 but only just got round to needing it so it is for all intents and purposes a new receiver. I am running Open Tx 2.2.4 original Accst version and have flashed the Rx to be sure of compatibility using RX6_LBT180516.frk No flashing red LED when the RX is powered up in bind mode, it goes to solid red and green. Not sure what, if anything, I am doing wrong as I'm following my normal bind procedure. Any suggestions?

That looks interesting Mike, not something I'd heard of but could be just the thing for the tiny slope ten minutes walk from my house!

Slingsby T31M from the Peter Miller plan:

With the arrival of the film from HK I was able to finish the covering, followed by the application of the registration lettering courtesy of my Silhouette vinyl cutter: Followed by glueing in the struts to the hard points: Windscreen was fabricated from 0.5mm PETG fixed with UHU Por and silicone sealant and silver metallic vinyl film applied to simulate the aluminium support. Which, apart from radio setup, completes the build: AUW 2.2Kg (or 4.85lbs in old money), she balances easily without any lead and with room for adjustment on the battery if needs be. Maiden flight probably won't be until the spring. Thanks to PM, she was a joy to build and I'm sure will be just as enjoyable to fly - looking forward to some low and slow flypasts!

Got myself ready to go out for a quick fly today, checked my Tx only for switch SF to fall apart as I moved it. As the particular model I was planning to fly doesn't need this I took the Tx apart, removed the loose parts and taped over the hole. Came back from my flying session and noticed switch SB was loose so went to tighten it up only for the same thing to happen. I use SB as a rates switch so don't really want to be without it. Sods law of course comes in to play as tomorrow is forecast sunny and 13 degrees here (rare opportunity for this time of year) so was planning to go for a longer session at my club airfield. Grrrr! I've ordered some replacement switches but it's rather knocked my confidence in the radio and left me wondering why this has happened. They do seem to have a habit of coming loose and require occasional nipping up, I wonder if my tightening has been over zealous, or is this a common problem? These are the bits it separated itself in to:

Having calculated I had just enough Carmine Red to cover the wings I find I'm fractionally short so whilst I wait on HobbyKing it's back to the fuselage. After a further two coats of Oracolor I moved on to the fiddly bits, first I fabricated the leather cockpit coaming using some leftover log burner rope gasket covered in masking tape: Along with some spruce finished with Danish oil and a piece of foam to simulate the head rest I have a reasonably atmospheric cockpit: Rudder servo installed and Rx mounted alongside: Tailwheel and closed loop detail: Motor mounted and secured with thread lock, I've retained the side and down thrust, I can always change it if I feel the need. ESC floating free in the battery bay: Registration lettering added: And with the wheels finally on that's the fuselage pretty much complete, apart from the windscreen which I haven't yet figured out how I'm going to secure it:

Very interesting Graham, is this the FT foam board with brown paper covering that you are using? I ask because I have a stock of it so could be tempted in to having a bash at something like this at some point ........

Functional struts shaped to profile from spruce and wrapped in self adhesive vinyl. The "Robart" hinges will be bonded in to the hard points under each wing, the plans show modified plastic control horns for the fuselage attachment point, I chose to fit threaded eyes to give me some adjustment: Fuselage has received a first coat of paint, Oracolor brush applied. After it had dried I couldn't resist a quick rig up to see what it all looked like:

Wing retaining "click" fixings installed, female part bonded in and the male half threaded in to suit with the amount protruding varying the tension: They come with a wedge for prising them apart which will preclude the need for tugging on the more delicate parts of the wing:

Maximum heat! Do you use that temperature for tacking, sealing and shrinking? My covering iron is also of similar vintage with only a low to high setting rather than being marked in actual degrees of temperature.

I've started on the covering. Flying surfaces in HobbyKing Carmine Red, I know a lot on here rave about the HK film but I always seem to struggle with it, the iron either too hot or too cold (Goldilocks). it goes on but it's a bit of a fight, in the end I seem to do best using the iron to tack and seal and the gun to shrink. Fuselage is covered in Diacov and is now ready for painting, this is a lovely material to work with, goes on a dream with the iron and quickly shrinks with the gun:

I'm a lurker on this thread John but don't contribute as my skill and knowledge base for this type of build is way below what yourself and others have clearly demonstrated. However, I find the thread both inspirational and educational so I hope you can draw some sustenance from the knowledge that your efforts are not going entirely unheeded!
