The discontinued Multiplex Profi BB FET is a classic, high-performance analog servo from Multiplex's renowned "Professional" (Profi) line. This standard-sized servo is engineered for the highest levels of sport and competition use, combining a precise dual Ball Bearing (BB) supported output shaft with a powerful Field-Effect Transistor (FET) amplifier. The Profi BB FET is famous for its exceptionally smooth operation, high speed, and precision, making it a favorite for the flight controls of F3A pattern aircraft, high-performance helicopters, and as a top-tier steering servo for 1/8 scale racing. The identity of this servo is its legacy of refined, powerful analog performance. The FET amplifier provides a crisp, powerful response, while the dual ball bearings ensure this is delivered with flawless mechanical precision.
It is a true classic, representing a high-water mark in analog servo technology. For roboticists and animatronics builders, the Profi BB FET is a superb choice for applications where smooth, quiet, and powerful motion is required. It is ideal for creating the lifelike movements in a professional-grade animatronic figure.
