Airfoil Data
FX76MP160

The FX 76-MP-160 is a 13.9% chord-thickness airfoil with a maximum camber of 6.9% 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 -6.9°.

Thin airfoil theory predicts a stall angle near 10.9° and a peak lift-to-drag ratio around 71 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.

The FX76MP160 appears in the wing design of at least 3 documented aircraft, including designs from Rochelt and Pennsylvania. Its proven track record across rotorcraft designs makes it one of the more field-validated profiles in the UIUC database.

Designers evaluating the FX76MP160 typically compare it against profiles of similar thickness: LIEBECK LA5055 AIRFOIL, EPPLER 422 AIRFOIL, GOE 255 (MVA CA.6) AIRFOIL, NACA 2424, S1223 RTL. The FX 76-MP-120 is another reference profile frequently considered alongside it.
