Was flying today taking video and took my eyes off the screen. A few seconds later I looked down and saw a message that looked like it said MC battery low. I only caught a glimpse and it turned off. By deductive reasoning I am thinking it may have said RC battery low. If the batteries in my RC transmitter are getting low will it flash a warning on my screen? I was only about 5 minutes into a flight on a full battery and so far have timed myself by the clock and have not gone out longer than 15 minutes to be on the safe side. I will eventually trust the battery meter but for right now I am going with a clock. Any ideas?
