Mavic Air Won't start anymore

[Jcwww]

Problem?
Unit will raise about 3-4 inches, then lean to back and left until rotor hits ground

Was unit in a crash?
While landing, one of the rotors touched a wooden pole while the drone was a couple of inches above the ground. No visible damage.

What have you tried so far?
Replace both back rotors

What device are you using ( iphone , ipad, Samsung , etc)?
IPhone X

What firmware are you running ( aircraft, remote controller)?
Latest as of Sept 16th

What Go app version are you using? 4.3.1

Any modification? (if so what)
no

Did you change anything or install any apps? (if so what)
Litchi (same result when trying to start)

Do you have a video or pictures of the problem? (if so post link)
no

Any ideas? Seems like the back left motor is slower than the other three.

Ok, someone has to ask & I apologies in advance for insulting your intelligence, but you have put the correct props on the correct motors? Do the props turn freely at rest?

 

[Jcwww]

Don't worry I'm a total newbie so it's highly likely I do stupid things

But yes, they turn freely. BTW, the replacement rotors that came with the fly more combo all looked pretty identical to me

 

[flymorecombo]

There should be 4 with white marks at the centre hub & 4 without marks, Mavic should have 2 of each fitted on the matching motors. Sorry again if this is a bit obvious.

 

[Jcwww]

Oh ok. No I replaced like for like (without marks)

Thanks to both of you. I'm pretty sure I did it exactly that way but I'll double check

Come on, the suspense is killing me!

 

[Jcwww]

--> insert facepalm <--

Omg I feel so dumb right now.

I really mounted the wrong prop.

Thanks for helping, I'll hopefully post my first Litchi powered vid later today

 

[InvisibleName]

DOH!!!!

The props dont actually fit on the wrong motors. You cant lock them without breaking something on the bird or on the prop. Take a really close look at the mounting locks on both the new wrong prop you tried, and the motor this happened on!

 

[Jcwww]

Well they did - though not as easy as advertised should have been a warning.

Haven't had the opportunity for a test flight yet, way too windy (on holiday atCosta de la Luz, Spain)

There is a warning.... in the user manual! (Which, of cause, you’ve read??)

If you got the wrong prop on, it had to have broke something. Either the prop, or the mount on the motor, or both.

Dude does any of this sound as if I've read the manual?? Just the quick start guide. Yeah I know, pretty stupid in retrospective

Well the correct props were mounted pretty quickly. I'll test fly asap and let you guys know.

Thanks for bearing with me

Well, I like your honesty!

 

[Jcwww]

Reading the manual and still f***ing it up is probably even worse...

 

[Jcwww]

Ok it looks like I dodged a bullet - 2 flights without any problems

I would still very well inspect both the props and the mounts, maybe even replace them preventively. Given how you have to force to fit the wrong props on it's very likely there is some damage that could cause something to break after a while.
