I am looking to buy a radiocontrolled helicopter for my son who is 13. He has had a radio controlled plane before but it was very disappointing as it only lasted about 3 minutes in the air and had very poor control ( it also broke easily ! ).. We have searched the web and found a few between £20 and £70 but its very difficult from the on-line shops to know which is the best 'first' model to buy. I've seen the Picoo-Z, Dragonfly and mosquito all advertised in various guises.. Any help on which to choose .. or which to avoid !! Thanks
