The box was of my indoor (model) helicopter. It is quite sweet, ever so flimsy, and hard to fly.

Of course, helicopters are from everything I've heard, more complicated than a place, despite their inherent coolness. This simplifies things a bit by having too contrarotating rotors above each other, and a tail rotor that points *down*. By altering the speed of the two rotors you can make it not turn, or turn left or right. By varying the joint speed you can make it have more or less lift and go accelerate up or down. By turning on the tail rotor you can pitch the copter forward or back, and hence fly forward or backward.

But still, each of those adjustments has an effect on at least one of the others, so you have to constantly adjust to keep the two axes you're not trying to control constant.

After an evening spent playing I can make it go up and down gently, and turn, and fly it from my feet to land in a marked circle on the other side of my room.

It's fun, I get a kick out of doing it in real life, when in a computer game (which the controls are about the same as) it would just be frustrating. I'm glad I did get it.

ETA: I was going to post some pictures, but it's too hard to get one of it flying. Next time ewx or mobbsy visit...

Another useful criteria: books you actually sell.

Buying second hand is good, as is waiting for a publisher to publish in the uk, but "by this author, that I can buy today from you" seems a reasonable search :)
