The discontinued Airtronics 94743Z is a high-quality standard servo that offers a significant upgrade in precision and durability over basic bushing-equipped servos. The inclusion of dual ball bearings on the output shaft is a key feature that sets this servo apart, providing a smoother, more precise action and a longer service life. The ball bearings minimize slop and friction, resulting in a more connected and responsive feel for the user. This makes the 94743Z an excellent choice for a wide range of applications, from the steering and throttle control of 1/10 scale cars and trucks to the flight control surfaces of sport and scale aircraft. The servo's reliable motor and durable gear train provide a good balance of speed and torque for most sport-level applications.
The 94743Z is a versatile and reliable performer that represents a sweet spot in the Airtronics lineup. It offers a tangible performance improvement over basic servos without the higher cost of a digital or coreless servo. The servo's standard size and universal 'Z' connector make it a convenient upgrade for many stock RTR servos, offering an easy way to improve the performance of a model without breaking the bank. For the hobbyist who is looking for a reliable and affordable servo that offers the smooth and precise feel of dual ball bearings, the Airtronics 94743Z is an excellent choice.
