I had a Kyosho Dash 1 in the 1970th. It was a Porsche 917 body on mine. My car was painted blue.
Enya 19 engine if I remember correct. I had a Robbe 4 ch AM 27 Mhz radio with it.
Robbe in Germany sold it under the name K1.
Images below is from Robbe catalog and from front cover of a Swedish hobby magazine in 1971.
