also limit models speed reduce its overall lift-to-drag ratio L/D Therefore designing Slope Soarer higher velocities penetration thick highly cambered airfoils usually avoided design therefore usually sacrifices low-end performance maneuverability good friend Mike Mellor says What get top end give up bottom end think about statement makes sense months airfoil Quabeck 10/8 no exception aerodynamic principles however designed slope expeditions penetration speed arc emphasized 10/8 aiffoil section has 1% camber just 8% thick wont produce much induced drag wont have much profile drag either As result going high-speed cruiser airfoila section moves out its angle attack reduced cuts through high winds like hot knife through butter Further because its mean camber line low can provide good
