DB Name: MH 17
Family: Hepperle
Max thickness: 12.1% at x = 43.76% chord
Max camber: 1.4% at x = 30.06% chord
Available data sources:
JavaFoil+Calcfoil stall+Eppler ext transition
XFOIL ncrit=9
Notes:
Coordinates from TraCFoil.
Commercial use of the airfoil may be restricted by the designer's copyright.
Designed for pylon racing model aircraft (Q500 class)

Thickness: 12.13%
Smaller moment coefficient cm c/4 than e.g. MH 16.
Well suited for the Quickie 500.
Can be used at Reynolds numbers of 400'000 and above.
Developed for lift coefficients between -0.1 and 0.6.
Similar to the MH 16, but with almost zero moment coefficient (benefit: lower load on horizontal tailplane)
