Cool stuff. What do you mean by cool stuff? What I mean is the weird and wonderful strange rc models out nowadays.

The most exiting for me is rc skydiving. You strap your little skydiving dude to the bottom of a plane. Once the plane is upto a high altitude the small parachuting dare devil plummits towards the earth! Then at the last moment his parachute opens and he paraglides down to earth with you controlling him!
