       <long_desc>For altitude controlled modes the time from arming the motors until a takeoff is possible gets forced to be at least MPC_SPOOLUP_TIME seconds to ensure the motors and propellers can sppol up and reach idle speed before getting commanded to spin faster. This delay is particularly useful for vehicles with slow motor spin-up e.g. because of large propellers.</long_desc>
