Airfoil Data
GOE738

The GOE 738 AIRFOIL is a 9.8% chord-thickness airfoil with a maximum camber of 4.9% at 30% chord, suited to general-aviation and UAV wing design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -4.9°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 63 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 GOE738 typically compare it against profiles of similar thickness: MRC12, BOEING 103 AIRFOIL, S8036 (16%), MH 78 14.47%, NACA M15 AIRFOIL. The S4096 (designed for the E-flite UMX ASK-21 scale RC sailplane) is another reference profile frequently considered alongside it.
