This is perfect.
The only other thing I can think of to add is for instance, when you talk about a specific thing to look for, maybe show an image of what it is you are supposed to look for.
For instance, when you say look at the propeller, grab an image from google that shows the bad things you want to highlight. Obviously different things are more or less important to the viewer depending on their experience. Me for instance, I fly with props that are not, shall we say "pristine." I know what I can get away with because of my experience. A newbie might not have that knowledge.
That said, you need to be very careful in your tutorials to not suggest to anyone that they should fly with anything less than perfect equipment. Liability is a bitch sometimes.
But these are really good and you might consider other avenues for their exposure.
