I'm sitting here whilst my 7 year old son watches Netflix on the TV and I'm reading the forums and checking the weather forecast for flying tomorrow (might actually get some air time! Woohoo!). All of a sudden the Vision "low battery" klaxon goes off in surround sound in the room. I mean exactly the same sound. After recovering my composure I discover that my son is watching "Power Rangers: RPM". The klaxon sound is used by them as an alert sound when their computer sees the bad guys are coming. On further questioning he tells me they use it on other P-R spin-off series as well. Well that's torn it, because now every time my battery alarm goes off I'm going to have kung-fu, lycra suits and really bad monster costumes in my head. Maybe someone at DJI was a fan?!
