RE: Curare' airfoils
The templates shown are about right for that plane --we built them and then a jillion Tiporares using same templates.
The ailerons were the then carved block typereally not all that great but then we had no expo radios and std throws were minimal
The last versions I did had same root (fit the glass fuselages we made) and a thinner tip and shorter span - larger ailerons etc., much better plane but of course we had 20 years in between to sort it all out.
