Model Airplane Center of Gravity for Newbies

Model Airplane Center of Gravity for Newbies In this video I will cover all aspects of Center of Gravity (CG) concerning model aircraft for newbies Initial discussions will cover the crucial importance of having the correct center of gravity for your RC/free flight model airplane. In short, if the CG is not correctly located, the airplane will likely crash. Next will be a definition of what the Center of Gravity is, the concept of a range of CG locations and how one can determine if a model is level, nose heavy or tail heavy when balanced at the CG point. A further discussion of RC model airplane CG ranges follows to include the flight effects of a forward and aft CG, followed by a discussion of how the supersonic Concorde uses CG control via fuel transfer to safely fly supersonic. The symbol for the center of gravity, or sometimes called a balance point, on RC airplane plans is shown next. Following is a detailed discussion of how to compute a CG for a straight wing and swept wing. An important point in determining the center of gravity is just the chord of the wings is considered, and the CG has nothing to do with tail/nose moments (distances) or the plane's wingspan. The importance of locating the CG for ARFs is covered next. Finally, some design considerations for locating the correct CG without the need to add additional weight.
