Hitec HS-81 micro servo

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.

These servos fit straight in to the servo cavities in the 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 E-Sky micro, Multiplex NanoS, JR-375 and Protech B109.
