I've noticed a strange low tone beep after getting my CS8 up in the air. It's a sound that's transmitted through my Graupner MX20 headphones. I'm wondering if anyone has experience this right after lift off. Everything calibrates properly on the ground and all seems normal...
That is something with the new software. If you have voice it will say UP which sound like a beep. Happens about 6 feet or so off the ground?
I know what your are talking about, mine does it too. I actually got scared it was a low lipo warning or something and was freaking a few times when I first got my MX20
