MH 44

Low moment coefficient airfoil for tailless model aircraft
See also MH 45, MH 60.

Characteristics

Thickness: 9.66%
Comparatively high maximum lift coefficient.
Low moment coefficient Cm c/4.
Can be used at Reynolds numbers of 100'000 and above.
Has been used successfully in F3B tailless model airplanes.
Similar to MH 60, which might be better suited for Reynolds numbers above 100'000.
