Remote control airplanes or helicoptors - gets them outside with the children.
I have always had to buy my own and wrap it and put under the tree...
I may be buying my own GPS to place under the tree. Santa does not take returns.
You have to be careful with this one. I got a remote control speed boat for my birthday a couple of years ago. It runs on Nitro and just screams. The thing is they are a LOT of work to keep running. Before it was even started, a "friend" yanked the starter cord out and I had to fix it. Once that was done, I ran it for about 30 minutes before I crashed it and had to do some fiberglass repairs. Then I stuffed the bow into a wave and submarined it.
These things are almost as much work as a real boat, and men don't want gifts that require work!
Now a top of the line battery-powered RC truck/car/boat/plane/helicopter/tank would be cool.
