Hi, BlueBird is a Taiwanese company, it has no relations with Kyosho. They used to clone Kyosho buggies in the early and mid 80's, the car you are talking about is most probably a 4WD clone of the Vanning called Athena.

Did Kyosho make a brand called the BlueBird or was it its own company? I have just restored a BlueBird and all the parts and gears seem to be interchangeable with kyosho's buggies.
