It has a heater and ventilation system for all season flying. The aircraft can be built with an optional 3 gal aux fuel tank. The CX4's standard specified powerplant is a Volkswagen air-cooled engine. The design load factor is 3.8 g, with an ultimate load of 5.7 g.[2]
The CX4 first flew in 2004. As of April, 2017, there were 55 flying CX4s in Australia , Brazil , Canada , New Zealand, South Africa , and the United States . The fleet had flown 3316.6 hours total.[3]
