The Nipper got an Apache Micro Bladez, which was brilliant fun for the first half of the day. Then something happened and now it's uncontrollable; it just careers around the room in ever-widening circles until it crashes into something or someone. Everybody ducks because its like being attaked by a demented mosquito on steroids. The cat has fled to the front room as a refuge. I've tried to work it what's wrong but can't; I think either the rotor spindle has got slightly bent or the repeated impacts have damaged one of the blades, which are now out of balance. Brilliant little thing while it worked though, some incredible micro-electronics there.
