Holy moly, this kerosene-fueled full GFK* body RC speeder has a turbine engine that generates 40.50lbs of thrust at 125,000 rpm, letting it reach speeds over 450 miles per hour.
Perhaps even more impressive is that the pilot is able to maintain control at those speeds. Mindboggling!
* Fun fact: GFK stands for Glasfaserverstärkter Kunststoff, the German name for this type of glass-fiber reinforced component. I had to look it up!
