I am looking at building a 50cc Katana that has a flat 3/8" design for the vert and horiz stabs. I want to do a airfoil type one instead. I am wondering which airfoil to use. I got some info from another plane and that uses the NACA 0011, is this correct? If not does anyone know which one I should use for each. Any info would be greatly appreciated.
Thanks
If the flat plate worked okay for the designer of the model, the NACA 0011 (fully symmetrical, 11% section with the high point at 35% of the chord) will be functionally better. The improvement wouldn't be earthshattering though so don't expect some type of magical performance enhancement.
However, the NACA 00 series is a standard exponential curve airfoil and has terrific aerodynamic envelope. The NACA 11% on the wing is trully superior for the Katana. It's a great all around airfoil for aerobats of any size. Been using the 10, 11 and 12% for many years with superior results in the overall flight envelope of my aerobatic designs
