The Extra Flugzeugbau 300 and the Zivko Edge 540 are unlimited category competition aerobatic monoplanes. Stressed for ±10 G's these "Crotch Rockets" are capable of a 420 degree per second roll rate and a 3,700 foot per minute climb rate. The Zivko Edge 540X is the most common aircraft used in the Red Bull Air Race World Series – in fact all champions of the World Series have flown this aircraft. Patty Wagstaff, Top Female Aerobatics Champion of all times, has flown various models of the 300 in aerobatic competitions and airshows since the mid-1980s. Costing upwards of $1,000,000.00 per plane, because these are custom built planes, it is uncertain how many are currently flying. The Extra & Edge are also very popular RC Planes with modelers because of their excellent flying qualities.
This plane is made from Diet Mt. Chill Cans but can be made from any 12 or 16 oz Beverage Can.
