The RED A03-200 series is a derivative of the proven RED A03-003 engine model, developed for very high-altitude operation. This variant can be combined with the 500 and 550 hp power versions.
The 200-Series is equiped with the NORMAL category gearbox as the complexity of the aerobatic oil distribution is rather uncommon in high altitudes.
