About to DREMEL off stuck propellers on my Mavic Pro. Any tips?

[diversions]

I suspect that corrosion on the spindle has "welded" the prop onto the spindle. Thus the prop cannot move downwards to allow disengagement of the "hooks" that keep the prop in place. I'm thinking I'm just going to cut right above the motor flange face to essentially remove the hook from the prop. Am I being stupid? Will I be able to remove the bits of the hook from inside the motor?

So many questions.

Background: bought my third second hand Mavic Pro for a paltry $180. Works great. But one of the props is stuck. So yeah.

edit: after examining a prop, I think I'm just going to start cutting away at the props little by little. take whatever material I can take away without touching any other part of the motor (or drone, or my fingers, in general).

Have you tried the obvious yet? A drop of either WD40 or watchmakers oil on the tip of the metal spindle followed by gentle and repeated downward pressure on the plastic rotor hub to encourage release.

There is a metal plate and compression spring beneath the motor top casing - if anything is likely to have jammed due to oxidisation: it will be this assembly.
