Notes
- The discontinued Airtronics 94451Z is a 'Pro Contest' grade servo purpose-built for one thing: speed. This high-speed marvel is engineered for applications where the fastest possible response time is not just a luxury, but a necessity for control and performance. It is the ultimate choice for the tail rotor control on high-performance 3D helicopters, where its blistering transit time and precise centering allow it to keep up with the most aggressive tail commands from modern heading-hold gyros. The result is a locked-in, consistent tail that holds steadfast through even the most demanding of maneuvers. The servo's exceptional speed is generated by a high-performance coreless motor, which provides the instantaneous acceleration needed to deliver its lightning-fast response. This speed is transferred through a durable, dual ball bearing-supported gear train that ensures a slop-free and reliable connection to the control linkage.
- The 94451Z's speed-centric design also makes it a formidable performer in other speed-critical applications. It is an excellent choice for the steering on 1/12 scale pan cars and other lightweight, high-speed racing vehicles where its rapid directional changes can shave valuable fractions of a second off of lap times. For the pylon racing or jet pilot, the 94451Z provides the instantaneous control surface response needed to navigate a race course with precision or to execute high-speed aerobatic maneuvers with confidence. While it may not have the brute torque of its high-torque siblings, the 94451Z is a specialized tool that excels in its intended role, offering a level of speed and responsiveness that can elevate the performance of any model where speed is the name of the game.
