Airfoil Data
IST-MT1-24

The IST-MT1-24 is a 15.0% chord-thickness airfoil with a maximum camber of 7.5% at 34% 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 IST-MT1-24 typically compare it against profiles of similar thickness: GOE 652 AIRFOIL, FX 73-CL3-152, GOE 383 AIRFOIL, GOE 217 (MVA MK.12) AIRFOIL, IST-MT1-15. The OAF117 AIRFOIL is another reference profile frequently considered alongside it.
