How well does the V4, or any Llama fly in confined spaces? I'm looking for something to fly around at work on Saturday shift. It's a huge room, but filled with cubicles, desks and cabinets, so I need something that pretty much hovers on its' own & maneouvers easily. I've been flying a bunch of the micro 3 channe Air Hog-type, but they are difficult to really steer/control, especially when the light breeze from the room heat/recirculating air is on.
