Thanks for the pictures.

How long does the battery pack last before you need to charge or replace it? Do you get any kind of warning when the battery pack is getting low? In case the pack goes dead while you're up several hundred feet, can the helo auto-rotate to a safe landing? Care to test that last question? Poked around the website but couldn't find anything on battery pack life.

It sure looks fun and I'm beginning to go hmmm...
