A radio-controlled aircraft is an unmanned aerial vehicle operated through a trans-receiver module – one located at the controller’s end, other inside the aircraft. The following section discusses an RC aircraft mirroring a miniature cargo aircraft, the notable features being the glow-plug engine and data acquisition system (DAS) using an altimeter and first-person view (FPV) camera. The RC aircraft is equipped to perform tasks simulating payload airdrops and carrying stationary cargo. A RC aircraft poses similar engineering problems as involved in designing large scale aircraft, albeit at lower speeds. The airworthiness of a RC aircraft is established during the conceptualization, design and modelling, construction, assembly, and testing phases. Softwares such as NX Cad 12.0, ANSYS-Fluid, and XFLR5 were used while developing an airworthy aircraft. Reinforcements of Carbon-fibre during assembly were integrated to make the structure light and sturdy.
