In our thesis, we designed and manufactured a remote-controlled model aeroplane for wind tunnel testing. Using SolidWorks Student Standard, we created a model aeroplane that adheres to the limitations of the wind tunnel at the Faculty of Mechanical Engineering and a system that enables us to move its centre of gravity. We then 3D-printed it and equipped it for remote control. We tested it in the wind tunnel which confirmed the model's ability to move along its vertical axis and rotate around its vertical, longitudinal and lateral axis. We measured its stall speed and compared it with the calculated stall speed. The difference was
small indicating that we created a model suitable for accurate testing of other flight parameters. We can change the model's centre of gravity mid-air, fore or aft of its equilibrium position and therefore alter its flying characteristics.
