The UDI U12 is a large 3.5 channel co-axial helicopter. It spans 28 inches and allows you to fly indoors or outdoors. The built in gyroscope helps the aircraft stabilize itself in flight allowing easy controls for beginner pilots. The 3.5 channel allows you to maneuver the helicopter forward, backwards, ascend, descend, rotate clockwise, and counter clockwise. The helicopter is constructed of aluminum and abs plastic materials providing strength and durability. The onboard 7.4v 1500mah lipo battery provides good power and allows for 5-8 minutes of flight time. Control distance allows approximately 40 yards of reach. This gives enough distance for the large helicopter to fly. There are safety features built in which prevent overcharging the battery. A large 3.5 channel helicopter is easy to control and will make a great first helicopter for pilots of all skill levels and ages.
