It was born from CARL, a missionary. In order to preach the Gospel to primitive tribes, heal patients, deliver medicine and food to people in need of help, suffering from inconvenient transportation, he was born as an aircraft designer and dreamed of designing an aircraft that could help him complete his mission. So this "missionary" plane was born, the English name is "ANGEL", that is, in the need of help, he can appear, help people in need.

Excellent crossing, safety, short-distance takeoff and landing performance, so that he can reach many remote rural areas, mountain jungles and highways. He can quickly transport medical personnel, first-aid drugs and disaster relief materials to places in urgent need of rescue, and can also quickly transport urgent, critical and seriously injured patients from the scene to the first-aid base.

When natural disasters such as earthquakes occur, "ANGEL" aircraft can quickly transport rescue workers and relief supplies to the scene. Near the site, only a clearing of about 300 meters or a road with good clearance can be landed, which is fast, convenient and safe. ANGEL's strong landing gear and wide wing area enable it to take off and land ultra-short distances, in the wild.
