Airfoil Data
FX08S176

The WORTMANN FX 08-S-176 AIRFOIL is a 14.5% chord-thickness airfoil with a maximum camber of 7.2% at 37% 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 -7.2°.

Thin airfoil theory predicts a stall angle near 10.7° and a peak lift-to-drag ratio around 72 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 14% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the FX08S176 typically compare it against profiles of similar thickness: Eiffel 371 (Monge), AH 94-W-301, GOE 514 AIRFOIL, GOE 735 AIRFOIL, NACA 5-H-20 AIRFOIL. The GOE 330 (PFALZ 59) AIRFOIL is another reference profile frequently considered alongside it.
