Cool, cheers chap. My LED's flash too when it's getting low on power but in the daylight it's not easy to see. I read there is an audible warning mod you can add which might be worth me considering especially when I'm still learning. Got 2 x spare batteries on order but I also read it's not a good idea to fly for more than two batteries worth of flight time otherwise you can over stress the motors? Or is that an urban myth?
Brushed motors can get quite hot if running for an extended period which doesn't help their lifespan.
