Kaman K-Max is an active uncrewed cargo helicopter from Kaman, aimed at cargo and logistics work rather than consumer flying or aerial content creation. Based on the supplied data, its headline numbers are unusually strong for this category, with up to 12 hours of endurance, 1,852 km of range, and a top speed of 185 km/h. That makes it a model worth watching for enterprise, government, and research teams comparing serious VTOL logistics platforms.
