Sometimes I check and bet what I have found today.. I gently bend upwards to align where needed and that's it.

Not to mention always remove blades after flight session.

Edit: not to be done often and only if severe difference otherwise you'll add more metal fatigue.

Probably not a critical difference. I wouldnt be bending them up all the time. May do more harm than good.

Yep, would add more fatigue so only if noticeable difference and really needed. Good to check anyway including inside the blade. What I don't get is why some lower but other not. Now all on same spot and will monitor time to time.

There will be an acceptable tollerance, the fact there is more than one is reassuring.

Springs fatigue through cycling. Keeping them compressed won't damage them. Taking props on and off causes more metal fatigue than leaving them on all the time,

I have read some stuff and it seems that metal characteristics is important as to ideally support all the way down compression within elastic region for installating the blades, otherwise it will modify its plastic and not behave as originally intended. Plus number of cycles and orher parameters. Also manufacturer might change something in batch metal we don't know and not all equally looking at the same..
