maybe a little late but looking like you have tried everything apart from 1 basic check.
when in betaflight on the receiver tab have you got coloured bars upto 1500 on channels, if not reflash firmware .
Hello Dale, thanks for joining in.
I do have coloured bars on all of the aux channels.
On the modes page of Betaflight, all the channels (1 to 6) are able to go full to 2000
I don’t know if the following is any use, but I include it just in case it is, because I still cannot get the motors to arm

I tried to upload my betaflight backup files, but they are json files so I had to rename them to PDFs before I was allowed to send them. You wull need to change the PDF to JSON to read them properly, although they should still be perfectly readable as text files.

Using the above configuration, the only problems that Betaflight tells me about are CLI and MSP; neither of which should be a problem when I am not plugged in to Betaflight
Ok just to get the right…
AUX channels are working as expected now… 1000 - 2000 on the RX Tab
What about your - Roll,Pitch,Yaw and Throttle channels?
Can you do a screenshot of the RX tab and Modes tab?
Hi Doomed
I won’t be able to respond for 4 or 5 days, but I will get back to you with a screen shot
not a problem… I’ll or someone will still be here.
Here are the screenshots you requested.
I should point out that Aux 2 and 3 are only on full (as shown) when I flip switches ‘C’ and ‘D’
The Yaw is actually a connection from a servo motor directly to the RX channel 4. That works perfectly and I can switch the yaw from side to side, going from 1000 to 2000 via the TX.
I also include a shot of the CLI after a STATUS query
You don’t have a switch assigned to arm.
Try setting it to Aux 2
and when you switch it… the yellow marker should move
dont know if fixed yet but wont arm if throttle above idle value even if arming via switch. looks like throttle at 2000.
arm switch better but if running out of aux channels think you can still arm min throttle yaw right,
might be wrong on this point as not used for years.

Hi Doomed and Dale
I have set the arm switch to aux2.
The yellow marker does move and the centre point depends on the position of the switch ‘C’ On the screen with the switch off the marker is at about 1000. Middle position at 1500, 3rd position 2000.
On the motors screen, I notice that the first block is now at zero; this can be moved with the throttle on the transmitter.
On the previous post, I put the throttle to 2000 to show that it works.
So just to refresh, the problem is that you cannot arm?
The quad will not arm if connected to betaflight due to safety. But if it still doesn’t arm while just connected to battery, this article will help narrow down the cause:
It just started working. 
I don’t really know why, it could have to do with my changing the arming range to 1075 - 2025 but I don’t really know.
This is just the beginning of course. I now need to know what I should do about the other things in the modes tab.
Thank you all so much for your help so far, I was getting ready to throw it all away. Now … sunshine all round 
Looking your last image it looks like your build will always be armed…
It should look more like this ( sorry for the rough screenshot, I don’t have a quad with me )
Your assigned arm switch should move in and out of the yellow arm area.
The areas can be a different size depending on where the disarmed and armed position of your switch is
White area = disarmed.
Yellow area = armed.

Hi Doomed
I thought that might be the case, but having finally got it to work, I didn’t want to mess it up again.
However, I have changed it a bit so that it is only armed at 1350 now.
The motors all seem to start at different times,some at 1350 and some about 1400-1450. Is this something I need to worry about, and if so, what should I do to rectify it?
I am really grateful for your ongoing help.
Sounds like ESC calibration to me…
Have a read and follow of this guide and let us know how you get on.
Hi Doomed
Thanks for that link. I followed the guide and the motors are improved a lot, but things didn’t all go as expected.
The ESCs never stopped making noises, whether it was the motors beeping or musical chimes, it just didn’t stop.
In the end, When the musical chimes started for the fifth time, I turned the motors right down got some different noises,but it still didn’t ever really finish until I just pulled the plug.
I tried several times with similar results, but overall, the situation is much improved.
What other modes do you think I need to set, and at what should I set them?
I will also look at getting the camera to work tomorrow.
Sounds like one of the ESC went though the programming menu so likely you have changed a setting on that one esc.
My suggestion would be to use passthrough mode to make sure all the settings between the ESC are exactly the same. I made a guide about it here:

I have tried on three different computers to get BLHeli to work. I have also downloaded new programs to each computer.
On ALL computers, I get the same screen that is just a blank.
I click on Read setup and the screen tells me it has done that, but no graphics appear.
Does this mean that the ESCs are NOT BLHeli ones.

I’m not sure if they are BLHeli or not.
When connected to BLHeli with your props off
you have to connect your lipo as well to power the ESCs.
You can also try the standalone BLHeli app.

Hi Doomed
Well, I downloaded and installed that version of BLHelisuite. It all installed fine and gave me the options of Atmel or SiLabs ESCs. It also has a tab for recognising whatever is plugged in to it. It didn’t recognise whatever it is that I have.
I went through all the ESCs that are supported, but I didn’t see mine anywhere.
I will write to the EBay seller I got them from and ask if they know what they are.
from your ebay description, i’m positive your esc’s are old simon k ones. yellow or blue plain heat shrink.
had some of these a few years ago when starting out. NEVER could get them calibrated, i even reset each one to factory default and still would not spin up correctly after calibration, i filed them in the B1N.
sometimes bite the bullet and get some decent ones.
I use the chaos 20 amp esc on my 2212. from unmanned tech of course.
