Airfoil Data
GOE243

The GOE 243 (MVA PR.3) AIRFOIL is a thick 16.4% chord-thickness airfoil with a maximum camber of 8.2% 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 -8.2°.

Thin airfoil theory predicts a stall angle near 10.1° and a peak lift-to-drag ratio around 74 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 16% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the GOE243 typically compare it against profiles of similar thickness: GOE 482 AIRFOIL, MI-STRUT1, USA 34 AIRFOIL, GOE 384 AIRFOIL, GOE 518 AIRFOIL. The E475 (15.01%) is another reference profile frequently considered alongside it.
