Hi all,
A month later, slightly better news
I've now tried mounting the AQ on the four M3 rubber damper I mentioned earlier, and the 'zing zing' noise has gone! I was able to hold a very stable hover in my small garden in slightly windy conditions. Also the platform didn't have its tendency of wanting to fly in a particular direction as it used to do here:

Interestingly, I've just spotted the 'zinging' noise in the MOT plots from my flights back in July – it's clearly visible as very sharp individual spikes. These spikes are *not* visible in the MOT plots from today's flight, but the MOT data is a lot more noisy.
I don't really know what to make of this – in one respect it's better, and in the other respect it's worse!
I will experiment making the mounts softer still and report back ... can't promise it will be immediately though
Many thanks for any and all advice,
David
