I just ordered my first ever p3 & I went with the 4k just so I could fly inside. I should be getting it on Friday (fingers crossed) I watch a LOT of YouTube videos of others getting there's & first flight & was wondering if there's any pointers from those of you that have been flying for awhile like when do I have to do the firmware update & how hard is it. Some say it's ok to charge both the aircraft & the remote at the same time, any advice? Little things like that would be helpful. Thanks & happy flying.
