Normal mode is suitable for fixed-wing aircraft. Soft or Very Soft modes are suitable for helicopters. The initial acceleration of the Soft and Very Soft modes is slower, it takes 1.5 seconds for Soft startup or 3 seconds for Very Soft startup from initial throttle advance to full throttle. If the throttle is completely closed (throttle stick moved to bottom position) and opened again (throttle stick moved to top position) within 3 seconds after the first startup, the re-startup will be temporarily changed to normal mode to get rid of the chance of a crash caused by slow throttle response. This special design is suitable for aerobatic flight when quick throttle response is needed.
