With my PV2 scheduled to arrive around 5:00 Pm EDT on Wednesday, I have been watching all the tutorial videos I can find. Also videos of people flying in places I would worry about and other "safer" places. The thing I am thinking about is the sound on some of the videos. I read somewhere there is no audio or a mic so no prop sound is recorded. But some videos have prop sound. I guess they could add it to the video at a later time but the "sounds" on these videos match or line up with different things the PV2 is doing. Makes me think they are recording the sound as it is happening. So, how are they doing it?
