Roam-e Prototype Available in 10 Days, page-83

Would a product like the Roam-e need approval before being sold, as an approval for safety? You got these propellers rotating at very high speeds near people and could collide with unsuspecting civilians causing cuts / gashes and thus the owners or company being sued.

You could be recording yourself in an area that is packed like a tourist hotspot, a concert, football game, etc and all of a sudden the battery dies and this flying projectile lands on someones head or something?

Also, what about the battery loosing power when it is in flight and just crashes on the ground and smashes your Aus$500 item?
