Airfoil Data
FX83W227

The FX 83-W-227 is a 14.7% chord-thickness airfoil with a maximum camber of 7.4% 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 -7.4°.

Thin airfoil theory predicts a stall angle near 10.6° 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 15% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the FX83W227 typically compare it against profiles of similar thickness: GOE 424 AIRFOIL, IST-MT1-21, GOE 242 (MVA PR.2) AIRFOIL, DEFIANT CANARD BL20 AIRFOIL, EPPLER 857 AIRFOIL. The FX 83-W-160 is another reference profile frequently considered alongside it.
