I have lost one of the front LED cover. A replacement is on the way, but about 2 weeks from now.
I am curious to find out if the Spark can still maintain its balance properly since one of the cover is missing, and the missing LED cover will cause some minute weight imbalance. I had 2 test flight just now and discover that the video is not balanced and tilted to one side. Could be because of the LED cover, or more likely the propellers or the gimble itself?

Hope to hear from you guys who can help.

Hi, sounds like it does has effect. What you can do is calibrate the IMU and Compass, and try again. Dont forget to calibrate again when you repaired the LED..

I doubt that it is the cover. Calibrate, like wimherman wrote, and try again.
On top, you can put some adhesive foil over it. But more to protect from dust and such

Hi. Thank you for reaching DJI Forum. Did you do some calibrations before the flight? However, it is not recommended to fly the drone with unequal symmetry.

Come on. Let's apply a little common sense here. The weight of that LED cover is insignificant. It will NOT upset the balance at all.

Correct.
But what happened to knock it off, will.

Thank you, someone finally mentioned that.

I'm thinking pmshop is right. What happened to knock it off?

Thank you guys for your advice

Appreciate it.
