Hitec HS-81 micro servos

How to Order
Back to Servos Main Page
Micro servos have become very necessary components of modern electric flight aircraft - the trend to have small servos directly driving control surfaces, or a servo on each aileron in a foamy flying wing, has raised the need for tiny, powerful and low cost servos.
The Hitec HS-81 micro is a popular servo for many applications, with respectable specifications. Compare the specifications below. These servos fit straight in to the servo cavities in the original Multiplex EasyStar and Easy Electric Glider - and they are a close fit to many other ARF electric aircraft, such as the Great Planes Slinger flying wing.
For smaller servos see the Multiplex NanoS/Hitec 55, JR-375 and Dymond D60 and Dymond D47 and FlyDream super micros
