Product Description
Now pay attention. If you're as serious about gadgets as we are, there isn't a great deal about the MX-1 that you won't be impressed with. First off... It's size. At an incredible 4 1/2 inches in length this is the smallest remote controlled helicopter you're ever likely to see, yet within its lightweight outer shell this helicopter houses a rechargeable battery pack and a minuscule propeller motor that enable it to fly around for approximately 10 minutes from a single charge. Charging the MX-1 is simple. Connect the helicopter to the hand held remote control unit and wait for the charging indicator to signify the on board battery is being charged. The hand held remote control doubles as a handy storage unit for the helicopter when not in use, enabling easy and damage-free transportation and simultaneous charging. Due to its size and weight the MX-1 is most suited to indoor flight and is ideal for flying missions around the office or in the home. Joysticks on the remote enable control of altitude, direction and trimming making airborne navigation as simple as possible.
