whats the problem!> any help pls

Hi there, sorry for the inconvenience. I would recommend to return it directly to the store where you purchased the drone or you can contact our support team using this link: (https://www.dji.com/support?site=brandsite&from=nav). Thank you for your support.

Only on upstart? But when you start the aircraft all 4 motors running? Bought mine last week and when turning aircraft on, 3 motors do a little move. Think its normal?

Hi. I'm sorry but that's not a normal move. I highly suggest you to kindly send it for replacement where you purchased your drone.  If you have other concern, please let us know. Thanks!

Hi!

I was mistaken. The 2 rear makes a little move. Please see my dropbox link below.

Is this a correct upstart?

Look at my post with dropbox link please ;)

If it flies fine, nothing to worry about.
