Idle up is a feature commonly found in remote-controlled model engines, particularly in RC cars and aircraft. Its primary function is to automatically increase the engine's idle speed when certain conditions are met, such as when the throttle is at a neutral position. This helps to prevent stalling, ensures smoother transitions to higher speeds, and improves overall engine responsiveness. By maintaining a higher idle, it also aids in better fuel flow and reduces the risk of the engine flooding.
