Airfoil Data
GOE217

The GOE 217 (MVA MK.12) AIRFOIL is a 14.9% chord-thickness airfoil with a maximum camber of 7.5% at 29% 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 -7.5°.

Thin airfoil theory predicts a stall angle near 10.6° and a peak lift-to-drag ratio around 73 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 GOE217 typically compare it against profiles of similar thickness: IST-MT1-15, IST-MT1-24, GOE 652 AIRFOIL, FX 73-CL3-152, GOE 383 AIRFOIL. The GOE 602 AIRFOIL is another reference profile frequently considered alongside it.
