Hi all, I'm hoping I can build a list of things to check for errors when I first buy my Phantom 4. I would buy it today, but it's rather windy outside, and forecasted rain all weekend. I want to buy it and immediately go down a checklist looking for possible errors, so I can get it swapped out before my 14 day period ends, as I'm buying through the Apple store. What is a quick list you guys would suggest I check? From what I gather, here are some common ones: GPS lock Gimbal level Flight time @20 minutes or more (I'm in the Rocky Mountains, so I don't expect maximum flight time) Active track working and follows a target General checking for errors on my Samsung S2 tablet in the DJI Go app Strange beeps Make sure 1080 and 4k video modes produce good quality video What else would you personally test or check to make sure your brand new Phantom 4 was good out of the box? Thanks!
