hi i m making a miniature aircraft...
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...
please suggest me which airfoil should i choose or any other airfoil which can be more advantageous...
