Paul, if you haven't already, get a V911. They're cheap as chips, weigh around 30 grams, and great fun to fly indoors. The V912 is similar but a lot bigger/heavier and, hopefully, will cope with wind outside. I've done a mini test flight in our lounge but it's an old cottage with low beamed ceilings and small rooms so it's bit too restricted. I fly the V911 in there quite happily, though.
I have a little quad, but it's definitely a no wind or indoor job. No danger of its affecting an airliner
