Airfoil Data
E180

The E180 (8.59%) is a thin 6.5% chord-thickness airfoil with a maximum camber of 3.3% at 34% chord, suited to high-speed UAVs, sailplane tip sections, and propeller blade design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -3.3°.

Thin airfoil theory predicts a stall angle near 11.9° and a peak lift-to-drag ratio around 54 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The slim profile minimises pressure drag at higher speeds but leaves limited spar depth for structural integration.

Designers evaluating the E180 typically compare it against profiles of similar thickness: NYU/GRUMMAN K-1 AIRFOIL, E221 (9.39%), NACA 64(1)-112, AG23 XC Bubble Dancer Root Airfoil, SD2030-086-88. The GOE 369 AIRFOIL is another reference profile frequently considered alongside it.
