P3S - After upgrading firmware, first flight out and the camera only records up to 30secs then stops and starts saving to the iPad, whilst its doing that I can't click to record video again. Back at base, although the timer on the record settings in Go app says 30 secs, actually the record length is only about 15 secs. Does the record cache settings make a difference, I've turned off caching to see if that makes a difference. Or Is this because I'm using a quite old iPad2 and the processing is taking too long? Or am I trying to record in 2.7k an its too high resolution for the iPad?
