Aerobatic Flight: Prohibited. The STOL series use a special airfoil design to achieve very high lift, low stall speeds, and high wing strength. Two, large lateral doors allow easy access, and offer removability for flight. " An airplane has a high L/D ratio if it produces a large amount of lift or a small amount of drag. Thank you for the article. Very interesting question. The offshoot is that a taller spar can be used with the Riblett, and in spar strength the height makes a great deal of difference because the section modulus goes as the square of the height and the section modulus is what determines bending. ” There is a LOT more to the LSA rule than selling planes. pdf), Text File (.
