Airfoil selection

  1. Apr 14, 2007 #1
    hi i m making a miniature aircraft........:frown: :frown: :frown:
    but i m struck with the problem of many......
    i have to fly my aircraft at about 20m/s(72km/hr=45 miles/hr) at about an altitude of 15-20m....
    wing span is 2m(it cannot be more than this acc to the rule of competition(fuselage also not to exceed 2m)), chord is 0.3-0.5m.........
    total weight is not to exceed 25kgs.....
    i have chosen S1223 & NACA8212, both give me over 200 N lift........

    plz suggest me which airfoil should i choose or any other airfoil which can be more advantageous.........:confused: :confused: :confused: :confused: :confused:

    Eppler is not bad when there is a span restriction
