This nano quad copter is the WORLDS SMALLEST! At under $40, this thing is truly amazing! With such a low price tag, you may not expect such a quality product; however, I can tell you, this little quad flies like a dream! It is very stable, and the connection between transmitter and receiver are instant. Very great control and easy to fly. It also, being so light, is very durable; I have crashed it numerous times with zero damage! One little quad everyone should look into!
