I have got two helicopters for my boys which do the same thing indoors. Haven't had a play yet, but I will. Have to make sure they're fast asleep - I left some early acquisitions for Xmas/birthday out on the landing on Sunday (Doh!) and they found them when they got up. I've ignored their questions thus far and denied all knowledge.
I bought one for my my 8 year old last year. Didn't manage to get my hands on it before he had bent the seemingly quite flimsy wings. It comes with a spare set, but haven't got round to replacing them yet
my little bro had a R-C helicopter and it was a right bar-steward to try and get it to fly. Its tail rotor kept failing, which meant it did take off but immediatedly crashed into the ground sideways as soon as it did.
His plane was a lot more reliable, but still hard to control - he crashed it into walls a few times and broke its wing! That was good though.
My guess is it will fly but will be quite hard to control - only really suitable for a large field or park. And don't underestimate the skill of actually doing the flying of it.
