Rc Helicopter choice…?

My sister and I wanted a mini rc helicopter (12 inches long MAX, it's gonna be used indoors only) for under $40. It would be nice if it had a flying time over 10min, and a reasonable charging time (30min max) Anyone have any suggestions?

I gave you a link to a R/C helicopter that I bought for my 8 year old son last year. He flys it with no problem and it is really stable, he even flys it outside when there is no wind.

I have purchased several different helis from this web site and have had no problem with them. Good luck!!!
