1. 旋翼：简介:直升机(helicopter)、旋翼(rotor)、悬停、与康达效应 (Coanda Effect)旋翼(rotor)由桨毂和数片桨叶构成. 桨毂安装在旋翼轴上,形如细长机翼的桨叶则连在桨毂上. 桨叶旋转时与周围空气相互作用,产生沿旋翼轴的拉力(这是主要的),

2. 摆锤：OMEGA用自产的摆锤替换了ETA的基础摆锤(rotor),(工作在小滚珠上的轴承)他们用MOEGA自产的齿轮传动装置和抗震调教替换了的自动桥. 减少了辅助换向轮和摆锤的高度差,同时也使得自动舵(oscillating weight's gear)的重量更加精确地与『撞击轮?

3. 分火头：分火头(Rotor) 分电盘里的零件,随着分电盘轴一起轴动,应用一金属薄片,将高压电送至火星塞. 钢板弹簧(Leaf Spring) 扁平长方形的钢板呈曲折形,以数片叠成的底盘用弹簧,一端以梢子安装在吊架上,另一端使用吊耳连接到大梁上,
