Overview

Charging over USB and flying by infrared, this green mini helicopter uses a built-in gyro to steady the aircraft in the air. It comes assembled with a spare tail blade and an English manual.

Two frequency options let two of them share a room, and the gyro helps with spinning. The limits are short flights, a transmitter that wants its own AA cells, and a title and description that count channels differently.

Who it's for

Living rooms and bedrooms with open air are where a palm-sized helicopter like this belongs, especially for a first flyer at the listed age. Outdoor pilots and anyone who wants quick recharges will be frustrated by the short flight and the long charge.

Pros and cons

Pros
  • Built-in gyro stabilizer
  • Spare tail blade included
  • Two frequency options for pairs
  • Low-voltage and over-current protection
Cons
  • Short flight time
  • Transmitter batteries not included
  • Channel count differs between title and description

Performance notes

A gyroscope system adjusts for spin in flight, which makes the aircraft steadier and easier to control. The infrared link needs a clear line to the transmitter, and the small battery limits each flight to a few minutes.
