Symmetrical Airfoils
NACA0006 to NACA0015
These are known as NACA 4-digit airfoils where the 4 digit number defines the shape. The first 2 digits define the camber amount and location. If these numbers are "00" then the airfoil has zero camber and therefore is fully symmetrical. The last 2 digits define the thickness of the airfoil as a percentage of the length. As an example, the NACA0006 is a 6% thickness airfoil, so an airfoil with a 10" chord will be 0.600" thick at the thickest point of it's profile.
The thinner NACA airfoils are popular for V-tails, Horizontal stabs, Fins and Rudders. The thicker NACA0012 and NACA0015 are popular wing airfoils for aerobatic and sport aircraft.
The original Bridi Kaos series of pattern ships used the NACA 4-digit airfoils and were some of the best flying planes of their generation. SD8020
