Airfoils come in several family. The most commonly used airfoils for flying model aircraft are:
- The wing of an aeroplane is actually made up of two surfaces, top surface and bottom surface, each with a different curve or camber.
- The technical name for such a wing is an aerofoil, and the cross-section through an aerofoil is called an aerofoil section.
- There are two reasons for curving the surface: first, a curved surface gives much better lift, and secondly, we must have thickness to give strength to the structure.
- But in RC Planes we can even use flat plates as wings.
- Flat Bottom
- Modified Flat Bottom
