In order to achieve casting quality at almost any level, degassing is essential. While various degassing techniques can effectively and efficiently Degas molten aluminum, the ability to measure gas content is essential in order to determine the most effective method. T. E. Aklin, Willard, and N. J. Davison of Robert Mitchell notes that while various tests have been used to determine the gas content in molten aluminum, the decompression test may be the most widely used test in today\'s foundry.

Outrunners in particular)Just spin the magnet ring on the stick. That\'s why they can make it so cheaply. Industrial Motors for general motion control such as servo systems and robots do not need to deal with changing transient loads, so they have some kind of feedback built into them. Typically, only models with built-in sensors are such small R/C cars and truck motors.
