*Product Use Statements: Although Sidewinder 4 is waterproof, it is not intended for operation while completely submerged in liquid. They can corrode when exposed to corrosive materials, such as salt water. Always rinse the ESC with clean water after exposure to corrosives or dirt. While the controller may be waterproof, Castle recommends users confirm that the rest of their vehicle, including the batteries, servos, radio and chassis are also waterproof before exposing them to liquids of any kind.
- Not all LiPos are created equal, and surge ratings should never be used to determine a pack’s suitability for a brushless application. Use the CONTINUOUS C rating only. Brushless setups frequently hit 100+ amps in peaks. Castle strongly suggests using 5,000mAh or larger LiPo cells with a discharge rating of at least 30C (or high quality 25C batteries). Castle suggests using only mild gear ratios with NiMH cells. Do not attempt to use NiMH cells in extreme setups.
