How to go near the ceiling in a factory with a 200 foot tall ceiling?
Everything working fine flying indoors except this.
Thanks.

Hi, thanks for the inquiry. The maximum flight altitude can be adjusted from 20-500m in the DJI Go 4 app and beginner mode should be turned off. However, we would recommend flying the drone in an open area without any interferences such as radiofrequency or metal object. Please refer to the screenshot below.

I had beginnier mode off but it would not accept the new number
I entered in Set Max Flight Altitude.

Do i have to enter the number while the drone is flying?

This is for a job in a factory.

Thanks again.

My guess is, you aren't in P-GPS, but in VPS Mode
Max height 5 or 6 m, right?

Be REAL careful near a ceiling! Get close and the magic forces involved will suck your drone up and stick it to the ceiling.

Yep, but just for a second!
After that, the magic forces spit it out and it comes quickly down!
The prop guards are a good thing to have, indoors!
