The discontinued Airtronics 94555Z is a 'Microlite Metal Gear' servo that combines the lightweight design of a micro servo with the durability of a metal gear train. This makes it an excellent choice for applications where both weight and strength are important considerations, such as the wing-mounted aileron servos in high-performance gliders and F5B competition models. The metal gears provide a significant increase in durability and resistance to stripping, ensuring that the servo can withstand the high-stress loads of these demanding applications. The 94555Z's coreless motor provides a rapid response time and a smooth, precise operation, while the all-metal gear set ensures a slop-free and reliable action.
The 94555Z's combination of low weight and high durability makes it a versatile and valuable component for a wide range of specialized RC and robotics projects. Its ability to deliver a good balance of speed and torque in a small, lightweight package makes it an ideal choice for robotic arms, grippers, and other applications where space and weight are at a premium. The servo's high-quality construction and reliable performance have made it a favorite among competitive pilots and builders who demand the best in micro servo technology. For those who are looking for a micro servo that can provide the ultimate in durability without a significant weight penalty, the Airtronics 94555Z is the perfect choice.
