The Sidewinder Micro, our popular affordable Micro controller, now boasts all new updated circuitry and added functionalities. The Castle engineers are committed to taking full advantage of advancements in component quality and continuous improvements in software design. As a result, Castle is thrilled to introduce the Sidewinder Micro 2. The Sidewinder Micro 2 is perfect for 1:18th scale 2WD vehicles and smaller 4WD (up to 2 lbs.) such as the Team Associated RC18B2 or Dromida SC4 SCT. Whether you are converting to a brushless setup or simply needing more power than your current brushless power system is putting out, we have a combination to fit your needs. The Castle 20mm 0808 Brushless Motors are a perfect companion to the Sidewinder Micro 2 and are available in 4100Kv, 5300Kv, or 8200Kv packages. Not sure which one to use? No worries, our 0808 Gearing Chart provides recommendations to ensure a compatible and efficient setup.
