The A320 model of Airbus was used to design the RC aeroplane. Client wanted a scaled-down replica of the the aircraft for this project. The design of the plane include the fuselage, the wings, the tail section and housing for the engine.
The internal structure of the wings and fuselage was also designed to ensure light weight as in the case of real aircraft. The spars and the ribs though not exactly but resemble the real structure.
