The airplane features light yet strong structure, low wing load, and abundant power, making the airplane easy to fly and capable of a lot of advanced aerobatics, such as all P3A and a few 3D maneuvers. This airplane performs very well in either low or high speed, with great authenticity and precision in response to radio stick movements, ideal for pilots who graduated from trainer airplanes to the next level of skills.
