Props: are we sure it’s just how we put it away?

So...
- I’ve not been using the FMC since the 28th of April.
- I have replaced all the props on the 16th of May (yes, I did crash into a bush while I was orbiting) with original parts.
- It flew about 4 hours since then.
- The MM has been left ”resting” every night into a shaped foam where the belly doesn’t even touch the bottom of the case.

- I’ve paid extra attention.

Today I checked the dat file, and the right rear motor (yellow) is always spinning a lot faster than the left rear one (blue). I recall this wasn’t the case just 2 weeks ago.
I think there’s something more with this props.

I had the motor errors come up after I'd not paid full attention when packing away and the prop guard was a bit tight.

Left it unfolded next to a window for a couple of days and flown my furthest and highest flight since over 4 batteries (after testing) with no errors. I believe the flexible props might distort when forced or tight, but will return to shape if left open.

If your attention is heads up on aircraft, the "on screen warning pops ups" are short enough it's possible to miss a warning. Removing the blades and closely examining them by comparison to each other is the only way to know if you've got a warped blade. In a previous post by premium pilot sar104 an excellent method for inspection.

I can’t see any alert even on airdata where everything is clearly notified.
Can I use the same screws again after the visual inspection?
 
It would be interesting to know the point between when you get a warning, and when you get an un-commanded decent ?
Maybe we need quick removable blades ? But that would probably put us over 249 grams.
I re-use the same screws several times. If I don't feel friction on the threads while turning them, I add some locktite.

Just asking but aint it a bit risky to put locktite on those small screws? I know locktite from the automotive world and in some cases you cant get a bolt lose without heat and a few meters of extension now what if that little starhead bolt strips?

I believe it's blue locktite on these, less heavy than the red
 
Have you ever wondered which marketing genius came up with the clever idea of selling Blue loctite in a red tube, and Red loctite in a blue tube? Like that would never present an opportunity for confusion. Brilliant, eh?

I can't quite read the instructions, does it say "squeeze into eyes to cure coronavirus"?

Early morning flight today, I've done some hovering test a couple of meters high from the ground. As you can see no input to the sticks, look at the rear right speed. Got back home and change these props, I will test again later today.
Honestly I don't want to wait for an error or an un-commanded descend to lose my MM on top of a tree or somewhere I cannot recover it.

For the logs, the old original props do look like new and were only 15 days old.
 
Where do i get access to that data? I only have the free oktofly acc where I upload the txt file how do i get the info like this

Follow up: I've changed the rear right props and everything got fixed.
So... It's not just how we put it away but "some" of the props lose effectiveness over time.

One propeller had flattened on the left side, I replaced it with a new one,no warnings. Flying well.
I stored legs open.
