“Straight And Level Flight From Your RC Model Airplane”

What Do I Mean By Straight And Level?

    If you have been reading this blog for a while, you have seen the phrase “straight and level flight”.  So, I think we need to talk in some detail about this aspect of RC flying.  Straight and level flight is somewhat self-explanatory, but to understand what it is all about and how to go about achieving it you need to understand some of the terminology of the subject.

    You may not be familiar with the terms of pitch, roll, and yaw as it applies to RC airplanes.  Pitch refers to the nose up and down attitude of the RC model.  It is affected by the CG or center of gravity of the plane and by the up and down movement of the elevator control surfaces.  The Roll axis is around the center line of the fuselage.  The roll is affected  by the left and right “bank” of the airplane controlled by the movement of the ailerons. And the yaw is the nose left and nose right movement of the plane controlled by the action of the rudder control surface.  These are the actions of the RC airplane that determine the direction and the attitude of the model’s flight.
