Abstract	This paper presents an accurate self-contained helicopter dynamic model, derived from first-principles, and that is specially tailored for model-scale helicopters. The simulation model includes the rigid body, main rotor flapping, and Bell-Hiller stabilizing bar dynamics. Particular emphasis is placed on the analysis of the stabilizing bar and on the evaluation of its impact on the overall helicopter dynamics. The model is parameterized for the Vario X-Treme acrobatic helicopter, and solutions for a set of trimming trajectories are identified and discussed. Different simplifications, needed to derive models for control system design, are presented, compared, and their influence on the resultant dynamics evaluated. The effect of changing the physical parameters of the stabilizing bar is also assessed. An LQ state feedback controller is synthesized to stabilize the vehicle in forward flight. Simulation results obtained with the full nonlinear dynamic model and the forward flight control system are presented and discussed.
