"      Car guys love to talk horsepower and top speed, but translating those specs to the sky requires a complete relativity recalibration. Witness, for instance, Red Bull&amp;#039;s recent F/A-18 Hornet versus F1 car drag race (top speeds: 1,242 mph vs 236 mph)-- or more even recently, my gut-wrenching aerobatic flight with Red Bull Air Race pilot Kirby Chambliss over the California desert. To non avgeeks, Chambliss&amp;#039;s chariot, the U.S.-built Zivko Edge 540, may seem grunty but fairly unexceptional. Packing a modified Lycoming AEIO-540 engine that cranks somewhere over 300 horspower, this carbon-bodied aircraft weighs just under 1,200 pounds. But when it&amp;#039;s punching through the sky it can climb 3,700 feet in a minute, roll 420 degress per second, and pull up to 12 brain-draining Gs-- and believe me, my brain got sufficiently drained of blood to make me wonder, for a moment, where I was and why the horizon was spinning. The pipsqueak plane&amp;#039;s got a symmetrical airfoil, so it creates just as much lift upside down as it does right side up-- which is perfect, because Chambliss just loves-- loves-- to invert. He&amp;#039;s also got a knack for seemingly physics-defying aerobatic acts like making his plane tumble end-over-end, suspending it in a nose skyward, helicopter-like hover, and jamming the rudder so it yaws at impossibly sideways angle. You can watch Chambliss tear through the atmosphere along with the Red Bull Air Force, helicopter guru Chuck Aaron, and the Blue Angels at this weekend&amp;#039;s inaugural LA County Airshow. You can also catch the entire 8-race Red Bull Air Race World Championship on Fox Sports 1, which includes two U.S. competitions: Fort Worth (September 6-7), and Las Vegas (October 11-12).
