Curt von Delius, using a modified version of his record-setting Level 3 airframe, crushed his previous M -class altitude record of 37,762 feet by flying it to a GPS-verified altitude of 45,328 feet AGL on September 19th 2008 and also set a new J -class altitude record of 19,758 feet on September 21st 2008, during the XPRS launch in Nevada s Black Rock Desert. The altitudes were recently certified by the Tripoli Contest and Records Committee. Scorched from aerodynamic heating after reaching almost 2,000 miles per hour, von Delius MMAX flight used an 8,060 newton-second, Kosdon by AeroTech Animal-Compatible (KBA A-C) M1450W reload kit (AeroTech P/N K13145P, $300.00 MSRP) that generates a peak thrust of 480 pounds during a burn time of 5.46 seconds. The rocket pulled 24 Gs and the time to apogee was 46 seconds, with the vehicle coasting for nearly 40 seconds after motor burnout.
