Airfoil Data
FX72LS160

The FX 72-LS-160 is a thick 16.2% chord-thickness airfoil with a maximum camber of 8.1% at 40% chord, suited to high-lift UAV wings, RC sailplanes, and low-Reynolds-number slow-flyers. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -8.1°.

Thin airfoil theory predicts a stall angle near 10.1° and a peak lift-to-drag ratio around 74 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 16% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the FX72LS160 typically compare it against profiles of similar thickness: EPPLER 862 STRUT AIRFOIL, DRAGONFLY CANARD, GOE 625 AIRFOIL, IST-MT1-18, Rhode St. Genese 36. The WORTMANN FX 72-MS-150A AIRFOIL is another reference profile frequently considered alongside it.
