Notes:


Coordinates from TraCFoil.
Commercial use of the airfoil may be restricted by the designer's copyright.
The airfoil has thickness of 9% and camber of 2.4%.
It's intended for Re numbers from 80k up to 800k, so
it can be good for R/C Soaring models as for F3B/J or
similar.


As the drag CD at lift of CL=0-1 is relative small it's good for
task A Duration, excelent for task B Distance and very good
for task C Speed in Multi Task Thermal Soaring Gliders F3B.
Caracteristics of model can be controled using flaps or
flaperons, but only with small deflections, because airfoil regard
good caracteristics without any controle of trailing edge. With
positive deflection of flaps more than +5 degre (down) max.
lift increase but drag increase very strong so as a good brake.
