The Aoyagi Metals Company was one of the more innovative RC manufacturers between 1979 and the mid 1980’s. AYK on-road cars dominated the Japanese race circuit and captured consecutive world championships in their peak from 1980 to 1982. Even though many of the on-road RC cars of this era looked the same, subtle differences in design specifications set each other apart. AYK, for example, had a creative differential design. Most manufacturers of this era placed their differential gears between the right rear wheel and the motor compartment. AYK’s unique design placed the differential within the axle itself. This not only centered the weight more proportionately, but also kept the differential gears well protected.
Towards their peak, AYK began manufacturing off-road buggies, both 2WD and 4WD. During their last years AYK began distributing their off-road vehicles in the United States through a California based company called Race Prep (well known for their electric motors). AYK came out with one of their most popular and competitive buggies under Race prep – the Radiant and Radiant Pro.
Ultimately AYK’s demise came with the death of the president of their company which ultimately led to loss of direction and eventually faded into obscurity.
