Yokomo YZ-834B

Introduced in 1983 for off-road racing, it has been cited by the website, LiveRC, as the first racing specific 4WD buggy[1] The car was marketed in Europe, sold by Graupner, as the Graupner Dogfighter[2][3][4] and in the US by Delta Systems, as the Delta Dogfighter.

[5] As the YZ-834B required numerous upgrades and an investment of US$500 (equivalent to $1,390 in 2023) to make it competitive, Yokomo introduced the mail-order only SE 4WD featuring a host of parts that made the car competitive straight out of the box for US$200 (equivalent to $555.92 in 2023) despite being offered with a Yokomo 05R stock motor and a mechanical speed controller.

[6][3] The RPS/Yokomo Dog Fighter SE was introduced following the 1985 IFMAR 1:10 Electric Off-Road World Championships win by Gil Losi Jr.
