Starbird, as far as I remember, was about a foot long and was equipped with a motion-sensor that would indicate whether you were diving or climbing. It was also equipped with two front flashing LED's accompanied with a laser sound.
The front cockpit actually detatched from the X-wing type rear-end, which was really cool as all the sound/light functions were in the front cockpit section.
Later on in the eighties they bought out an evil version of Starbird which was slightly smaller and black in colour and I think was called the Starbird Avenger.
For me the Starbird was a must-have toy of its time - I had one!
