You don’t need a large drone to have a fun flight. Take the AERIUS for instance. It is one of the smallest quadcopters around measuring 3cm x 3cm x 2cm. It has a ultra-compact controller and provides you with up to 7 minutes of flight time per charge. You get a 6-axis stabilization system and 2 speeds. The quadcopter has built-in lights for night flight. There is also a trick mode for cool flips and rolls.
AERIUS is available for $35 at this time. More information is available here.
