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-85MG micro is an up-market, slightly more powerful servo (than the 82MG). It offers a robust gear train and a shock-protected Pot. These are ideal for wing servos in the new breed of aileron and flap equipped gliders.
