The 24 Hour Race in Nürburgring is one of the most challenging endurance tests any racer can experience. Of course, we at DJI were there to capture aerial shots of this high velocity event.
Multicopter operations were conducted by professional pilots in coordination with manned aircraft pilots and authorities. Please always fly responsibly and follow the local regulations.
Note: The DJI Inspire 1 PRO Quadcopter with Zenmuse X5 4K Camera has recently been reduced in price; it’s now $ 3,399.00 (was $ 3,899.00).
