Now that I'm thinking about it, only a couple of the ESC manuals I have actually mention the throttle calibration sequence, but it has worked on all of the ESCs I have ever tried it on. Might be worth trying real quick before you get into the weeds with ESC programming.

If I plug in with the throttle set to full, it goes into the beepy beepy mode straight away.
I flew it on Sunday - the first one was great, though mid rates was well twitchy.
I crashed on the second one.
It felt like it wanted to bank left even after I straightened it up, but that wasn't the cause of the crash - that was when I turned onto the approach and pointed it at me, I lost orientation because I couldn't really see it, then when I did find it I clipped a tree. The tree didn't do any damage, but it fell onto it's nose. The good bit is that the design has the nose as a sacrificial part, so I can just replace the nose and it will be good to go again.
Without the wing aerofoil mod, it's really hard to pick out when pointed straight at you (especially with the white/grey sky we had yesterday).
Might post a picture of the damage later, I haven't taken any yet...

I sorted the throttle response this weekend (I think previously I was putting full throttle rather than half at the proper beep point), so I got to fly it again today. It was quite windy, and it grabbed the plane when turning a couple of times, but otherwise it was pretty successful. I got 3 good flights in, though I knocked the nose off (without damaging it!) on landing the 3rd time. I also discovered I had my rates the wrong way around, so when I thought I was on low, I was actually on high! I think that might explain the twitchyness!
It got me wondering - what would it be like scaled up with a seriously powerful EDF? How about a 140% version using 9mm depron and a 90mm fan? If I were to do that, I'd be tempted to make the wing double thickness (18mm) and then sand an aerofoil into it. @The Fopster Have you tried a bigger version?

It was destroyed on Friday. 😭
Super hot day (36, which is hottest day this year), left it in the sun until about 1pm when I flew it. Took off ok, fine on the downwind leg, banked into the turn for base and it lost power (audibly), and servo control, and plummeted to the ground. Smashed the esc and battery and edf out of the airframe! The motor and esc were really hot to touch, even after the walk to get it.
I had another EDF go down the same day, so I don't know for sure, but I think it was heat related.
I will build another, possibly modified to take a bigger fan, and definitely modified to have airfoil wings and a smaller cross section.
