hi there everyone today we're going to take a look at a very common area on a mavic mini where it
states propellers are rotating too fast and check your esc's if it's warps or there's any damage to
it so for most people the error is going to pop up just after takeoff but it can actually happen at
any time while you're flying and for some that could mean that they are quite a ways away from
the takeoff point as you can see here i'm going to just hover and then fly forward and then backwards
and then suddenly the area is going to pop up the area states propeller rotating too fast and
i must check my esc's as they might be damaged or warped now this can mean that your actual motor is
damaged and the most guys are just going to be completely freaked out and they're going
to think that drone is unflyable when in fact it's actually quite easy solution when you land
you're going to see which motor is beeping and in this case you can see it's the bottom right from
the rear and the other motors are 100% fine they aren't moving they aren't beeping and there's
nothing wrong with them whatsoever at the bottom right you can still see the motor still beeping
and moving around that tells us that is the motor in question let me take a look at now please don't
be worried about the motor moving by itself it's just warning you which motor is the problematic
motor so let's go and take a look at the motor as well as the propellers and sure enough here
we can easily see that the one propeller has got some damage on it now i'll explain a bit later on
what could possibly have caused it and what the easy solution for that could be but first let's
just quickly remove this propeller it's quite easy all you need to do is just remove a single screw
because remember we've only identified a single propeller as a possible concern so in this case
i'm just going to remove it and then replace it but when you do replace a propeller make sure that
you replace the correct propeller on the correct motor in this case there's no mark above the motor
but take a look at the other motors you'll see some of them have little lines on them and above
the motor there's going to be a little line as well so there's a line on propeller and there's
a line above the motor those propellers have to go onto the same motors and same area do not mix them
they have to go together as you can see over here the one propeller has no mark on top of it
and the other ones have you can see both propellers are the same no marks on it
meaning they are on a correct motor so let's just quickly attach this propeller to the motor
and the way that i like to do it i put the screw inside of the propeller i bring it closer over the
hole and i put some pressure on it by using the screwdriver that's applied with the mini combo
now once you tighten it make sure it's nice and tight and then be sure to check your propellers
in this case you can see both of them still look very good there's no dents or scratches or
any marks on them so they should be ready to go for test flight now remember the only thing we've
done is replaced that single propeller so let's just quickly take off and see if the area is gone
there we go drone takes off and you'll immediately hear there's a difference in the tone of the
propellers as well the previous one had a bit of a higher pitch and this time the propellers
are making a bit more of a normal noise that i'm used to before this issue started occurring now
it's not always a damaged propeller or an easy to spot damaged propeller it can sometimes just be a
warp propeller so swap out your propellers maybe just move from one motor to another motor and
then check if the issue has been resolved but now let's take a look at what could be the possible
causes of this and in most cases it's probably going to be the way that you package the drone
now if you've got a single unit without a fly more case you might have a different bag and you could
have the same issue that occurred there i'm just going to explain how it happens with the flymo box
if you fold up your drone and you put your arms away and you're trying to pack away the
propellers as nice as possible you try and put them into the case without it bending or getting
any pressure on it so in this case you can see i'm just going to move the blades around and make sure
that they don't get too much pressure and then i'm going to try and put it in the case now you
can see immediately the one blade went sideways and i had to retry and put it back in the case
and it slots in quite nicely now remember if you take out the drone again everything seems
fine you don't even notice that the propeller had some pressure in it while it was in the box
so this is an issue that can sneak up on anyone and the flymore case itself has been found to be a
possible cause of these issues now if you found this video useful please consider to subscribe
