Im fairly new in helicopters and I bough a Blade a while back. Ive had plenty of succesful flights in my garage running the battery all the way down. I just noticed that when flying my Blade the led turned from green to red inflight. I landed the helicopter and when I looked the led was back to green. I not sure how or why this happened there is nothing in the instructions that say about the led turning red. Ive held my helicopter down and at about 80% of power the led turns red

Can someone try running thier helicopter with low battery and see what happens to the led
