Aeromodelling generally involves small-sized flying objects like Radio Controlled Aircraft (RC Aircraft), Gliders, Ornithopters, Boomerangs, and Paper Planes. Although Aeromodelling looks like a lot of Aerospace/ Aeronautical engineering topics, it involves a lot of interdisciplinary concepts from various streams of engineering - primarily Aerospace/ Aeronautical, Mechanical, Electronics, Electrical, and Computer Science. Aeromodelling gives a good understanding of the roles each of these engineering skills play in the real aircraft industry and provides enormous opportunities to develop innovative thinking and implementation. While designing an aeromodel is highly based on engineering principles, flying part of Aeromodelling is also considered to be an expensive hobby/ sport.
