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-82MG micro is a popular servo for many applications, offering a robust gear train and slightly more power at a lower cost. These are ideal for wing servos in the new breed of aileron and flap equipped gliders – like the Cularis, Pulsar etc. Note – for extreme applications, more powerful servos might be required – see the KST-HS08.
