I would venture to say he's done that for a while. It would have been a surprise for someone to come around a corner or out a door way as it flew through the house.
Ha, that's funny that you posted this guy's video. Whenever I need to show off what FPV is really all about I usually show one of his Kangaroo fly by videos. Cool stuff.
OK, so my first thought was "this guy's gay". 'Cause no wife in going to let you fly your toys in the house and around her kitchen (lol). But then the kids came into the picture, then the wife unloading groceries from her car. So OK, the guy's straight - but where do people find these women!!! I kept waiting for him to make a low-pass trip down the river - oh well. Very good skills
This is one of his most popular videos. Gotta love the kangaroo investigating at the end. [youtube]http://www.youtube.com/watch?v=7yTqjxDQP_Y[/youtube]
