I'm getting intermittent red blinking on the led near the start of flight - 2 or 3 at a time. Only seem to get this in the first 30 seconds to minute of flight. Not sure if its GPS or if's some sort of battery alert / power draw as its usually while I'm full power trying to get altitude. Any idea's or has anybody else notified this? A whole lot more concerned if its losing GPS. As It locks on pretty quick on the initial power up and I always wait for Home point confirmation / seconds set of rapid green led's. Seems to be running fine after that and no more led's until LV warning. Anything to worry about?
