The purpose of the present work is to evaluate the flying qualities of a half-scale radio controlled airplane based on the Unmanned Airplane for Ecological Conservation via flight simulation. The stability coefficients of the half-scale airplane were obtained by vortex lattice method using the code Tornado. The radio controlled aircraft simulator CRRCSim was used to perform the virtual flights. Aerodynamic, geometry, thrust and mass characteristics of the airplane were introduced to the simulator by a code written in C++. Virtual test flights were carried out and the flying qualities were obtained. It could be concluded that the half-scale airplane has excellent flying qualities, rating the aircraft in level 1. The simulator is recommended as a training tool for test pilots of the real model.
