Went up town to the sales today and bought a helicopter. It is a twin bladed Chinook type thing, which was knocked down to fifteen quid in Red5. Number one son has shown quite a talent for flying the thing, which seems a lot more controllable than the single rotor ones that we had bouncing off the furniture earlier this week. He can actually make it hover in one place and it has this fancy way of tipping the front rotor to make very controlled turns.
I think these will sell out real quick, but if you get the chance to buy one I'd recommend you do.
