Airfoil Data
MH126

The MH 126 25.0% is a thick 20.1% chord-thickness airfoil with a maximum camber of 10.1% at 41% 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 -10.1°.

Thin airfoil theory predicts a stall angle near 8.8° and a peak lift-to-drag ratio around 79 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 20% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the MH126 typically compare it against profiles of similar thickness: EPPLER 864 STRUT AIRFOIL, GOE 531 AIRFOIL, KENNEDY AND MARSDEN AIRFOIL, S9104, S9104BTE. The EPPLER 546 AIRFOIL is another reference profile frequently considered alongside it.
