So I have a wedding from tomorrow noon onwards (I am a professional photographer) and my P4 shipping status shows it should be here between 8am and 12pm...

I'm not overly bothered as I have my P3 and I don't generally use drones as part of my wedding package, but if it turns up in time, what are the steps I need to do to get this thing up and running quick-smart?

This wedding is being held in a small mountain restaurant surrounded in snow and I was thinking an aerial shot or two could be fun.

You need to update the firmware of the P4 to the latest 1.0.0.288 version and the remote to the 1.5.80. Install the latest DJI GO app, check the release note and user manual.

Cool. That's it?

Although I am thinking even if it does arrive in time, it'd be silly to use it straight away work-wise without playing with it a little. Not going to rush anything with it.

Thanks though Amy...
