In many unmanned aerial vehicle (UAVs)-related engineering projects, flight dynamics modeling of the controlled platform usually forms the foundation of the whole project development. An accurate mathematical model of the controlled UAV not only makes high-performance model-based control law design possible but also provides insights into the mechanical design of the aerial platform so that radical improvements can be made at the beginning of the development. However, the topic of flight dynamics modeling is somehow not paid enough attention to across the general engineering audience. This chapter aims to disseminate the knowledge of systematic modeling of UAV flight dynamics by talking about UAV model formulation, parameter identification, and model verification. The methodology of UAV model formulation and parameter identification based on the case study of two kinds of coaxial helicopters will be explained. Modeling of coaxial helicopters, despite the common governing kinematic and dynamic principles, deserves special attention due to their distinctive mechanical structure and aerodynamics behavior. The modeling procedures and parameter identification process presented in this chapter also serve as a guideline for modeling other types of aerial vehicles.
