The discontinued Align 18G is a robust and reliable micro servo that offers a significant step up in power and durability from the ubiquitous 9-gram class. This servo is an excellent choice for larger park flyers, small electric sport aircraft, and the elevator and aileron controls of 450-class helicopters that require a bit more torque and a more resilient gear train to handle higher flight loads. Its sturdy construction ensures it can withstand the rigors of regular flying and less-than-perfect landings, providing pilots with a greater sense of confidence and security in their model's control system. The 18G's performance characteristics make it a versatile component for a wide range of modeling and robotics projects.
For the robotics enthusiast, the Align 18G's increased torque and durable build make it a suitable actuator for a variety of tasks that are beyond the capabilities of smaller micro servos, such as operating grippers, panning and tilting medium-sized sensors, or driving the limbs of smaller robotic creations. The servo's straightforward analog design provides a smooth and predictable response, making it easy to integrate into a wide variety of control systems. The Align 18G represents a sweet spot in the micro servo category, offering a compelling blend of power, durability, and affordability for the discerning hobbyist and builder.
