Size matters. The bigger they are, the harder they fall, so now there's a chopper that is more resistant to fall damage than ever before. Introducing the Odyssey 7500 Quark Micro Copter -- an RC helicopter that's about the size of your thumb! Speed and swoop over sofas and down stairways, practice your landing skills, or create your own indoor stunt course. The Quark is fully assembled with all pre-flight adjustments completed. Simply remove it from the box, insert the batteries, charge directly from the controller, and get ready for take-off!
