I fitted a new red prop mount last night, and this fixed the problem for me - no more rattling when I spin the props.
This has fixed it for both old props and new props :- while the new foam filled props did make the situation better, I felt these were just mitigating loose mounts, and feel more comfortable fixing the root cause.
If I had fitted (on the red engines) the white clamp instead of the red one (still using the red centre part of the mount) that would have made it even tighter, but the new red ones seemed almost tight enough, certainly miles tighter than the old red one.
I also recalibrated the IMU - before there seemed to be some noise on accelerometer 0 (compared to accelerometer 1), but after the calibration that had gone away. I'm hoping that has fixed my minor stability problems. I did quickly test fly it afterwards, and I imagined it was better, but it was very windy so was not really possible to say.
Note that when recalibrating the IMU, I had a problem when it asked to tip the drone forwards onto the table by 45 degrees, that I couldn't because the camera was in the way. I had the 42mm with a lens hood, so either that combination was too long, or the camera should have been tilted upwards a little more before I started the calibration. I am not sure which as I changed both the lens (to the 15mm) and the camera orientation, before restarting the IMU calibration.
