Aircraft
The competitors use high-performance aerobatic planes such as the Zivko Edge 540, MXS-R, and the Corvus Racer 540, equipped with Lycoming engines. All aircraft have a wingspan less than 7.6 metres (25 ft) and top speeds ranging from 406 to 426 km/h (252 to 265 mph).
Competitors have tuned their aircraft for better performance. However, the safety implications of engine or airframe failures mean that performance tuning by individual teams, though commonly done in motorsports, is strictly limited in scope.
Each aircraft carries a TL Elektronic TL-3424_EXT accelerometer. It transmits timing and speed data which is picked up and displayed on large spectator screens.
