Will try to get more flight videos on the Mi Drone 4K.


Final thoughts
A great stable flyer. Easy to learn and fly. An improved version of the problematic first version during the initial release.

It’s value for money and high price-performance ratio than getting drones from DJI or Yuneec.

I can’t compare with other drones like DJI or Yuneec as I don’t have the drones to compare it with. I did fly my friend’s DJI Mavic Pro a couple of times before but haven’t really got familiar with it.

Nothing to dislike about the Mi Drone 4K at the moment. But on one of the remote control’s antenna have a hairline crack. Wonder how that happened?

Can use. The Mi Drone app using Google map.

I think that was the initial launch Mi Drone.

Have you updated the firmware of the Mi drone? Also the Mi Drone app.

Best if you can contact the seller you bought it from for advice. Or ask in Xiaomi Fimi forum.

I got 3+ firmware updates since I got it in December 2017. I got no issues flying in KL and Ipoh. I think it's first Mi Drone version issue with yours.

Can see the propellers because I'm flying full throttle at 16m/s. If flyer slower then won't see it as the drone won't be tilted too much.

All drones can see the propellers when flying fast even DJI.
