Airfoil Data
FX74130WP1

The FX 74-130 WP1 is a 10.3% chord-thickness airfoil with a maximum camber of 5.2% at 47% chord, suited to transonic and supercritical wing sections where aft-camber reduces wave drag. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -5.2°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 64 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 10% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the FX74130WP1 typically compare it against profiles of similar thickness: GOE 388 AIRFOIL, I.S.A. 961, 74-130 WP2 MOD, GOE 165 (MVA MK.11) AIRFOIL, GOE 650 AIRFOIL. The FX 60-100 AIRFOIL is another reference profile frequently considered alongside it.
