This is my review of the SJ991 message writing helicopter. This is a 3ch infrared-controlled coaxial helicopter which uses LEDs to display messages. It comes with Windows-only software that can be used to program the messages (note: software does not work on a Mac!). The messages work well, but the helicopter flies very poorly, and is not very durable.
