The first model of the Ravenspear series of fast, high-altitude aircraft, the Mk1 is fitted with three engines: One central one that is most efficient at low altitudes, and two high-altitude ones that come into their own at 5km and higher. Its canard design has been called "very flyable, actually" by a few famous test pilots, although they also warn of the tendency to strike the tail on takeoff if pulling up too eagerly. Although they remark "it's good that there are more engines, if you break that middle one".
