Aerodynamics definitely play an important role. This is because if the plane is not aerodynamic then wind can easily slow down the plane. This would be bad because it could cause the plane to crash. Also the materials that the plane is made of. You don’t want it to be so heavy that it gets weighed down. But at the same time you can’t have it to light where impact to plane is more likely to happen. The wing shape definitely matters because as I mentioned previously they play a big factor in aerodynamics. The planes parts matter because you can’t use just any part for the plane. You also have to take into consideration how each part effects the materials and other parts. Lastly, the plane length. This is because a bigger plane could be not as fast as a smaller plane. The bigger plane could be more durable then the smaller plane or vise versa.
Hope this helps! If not I am very sorry!
