This radio controlled jet beats the pantaloons off anything we ever had as a kid. The Gruapner Hotspot Jet goes up to 200MPH and has a Jetcat P80 turbine on the back. The best part is that actually sounds like a jet. Be careful buzzing little Susie's house with this one—one wrong move and you're in for three counts of manslaughter.
