KO Propo PS-51S

KO Propo is known for their very fast PS-87 and PS-1001 FET servos for 1/10 and 1/8 scale cars. But most racers won´t know they also released small servos for 1/12 scale cars in the early 1980’s. The PS-51S and the PS-51BS both were introduced around 1982, the same time frame as the wellknown Novak NES-1A. KO Propo’s specs for the PS-51S is .20 sec for a full 60° travel where the PS-51BS was slightly faster at .18 sec.
PS-51BS servos came with our Mugen K2-X Cosmic GP/M 1/12 scale car.
