This airfoil has thickness of 10%, and camber of 4%.
It is intended for all FF airplane models for low speed
with Re numbers from 40,000 and more.
Airfoil must have appropriate turbulators at the top and/or
bootom side to provide turbulent flow on up side from
30%c and on down side from 5%c. By some models, they
fly only with higher lift, turbulator on the bottom side is
not need. To make turbulators more effective at small Re
numbers, on the top side invigators after 50%c are
Because of relative big thickness of 10% it is easy to
build models also with wing of high aspect ratio
to the conventional mode with wooden spars.
Drag coeficient CD at zero lift CL=0 is very small in
comparison with usualy airfoils wit high cambers, so
the model can be suitable for succesfull vertical launching.
