Estes describes the Syncro as the "smallest quadcopter in the world." It is small enough to fit in the palm of your hand, yet it features sophisticated technology including a full 4-channel 2.4ghz digital radio transmitter, a rechargeable LiPo battery in the helicopter, and bright LED lights.
Designed for indoor use, the Syncro is easy-to-fly. Its digital radio control system allows you to fly your Syncro at the same time as others without interference. A USB cord is provided to recharge the battery in the Syncro. Flies for about five minutes on a charge.
Two AAA batteries, not included, are required in the transmitter. Four spare rotor blades are included.
