The discontinued KO Propo PS-702 FET is a high-quality, standard-sized analog servo that has been a long-standing favorite in the RC community for its smooth, powerful, and reliable performance. As part of the esteemed "Professional Servo" (PS) line, it is engineered to a much higher standard than basic servos. A key feature is its use of a Field-Effect Transistor (FET) amplifier, which allows it to handle much higher currents than standard transistors. This results in a servo with a more potent and responsive feel, with stronger holding power and a quicker reaction time. The PS-702 is a fantastic, all-around performer for the flight controls on .40 to .60 size sport and scale aircraft.
The character of the PS-702 FET is its refined, powerful analog feel. For the pilot who prefers the traditional smoothness of an analog servo but wants a higher level of performance, this servo is the perfect choice. The FET amplifier gives it a boosted" feel providing a more direct and confident connection to the model. It is a classic high-quality workhorse that has been trusted by discerning hobbyists for years.
In robotics the PS-702 FET's robust electronics make it a very reliable actuator for a wide range of tasks. It is an excellent choice for projects where the servo might be subjected to higher-than-normal loads or where a high degree of reliability is required. It is a premium building block for creating more robust and capable robotic systems."
