Some of them starting to get a bit noisy, but still borderline acceptable for me.

Are these still acceptable? I've sort of tried to cut back on the slight adjustment I made for the last batch which resulted in some starting to get a bit noisy.

Same as before, borderline soft. Noise is only really an issue for #4, and I'd suggest lowering the ISO next time you shoot on a sunny day like that. No need to have ISO400 & 1/4000 shutter speed to capture these aircraft.
