Aerodynamics - Blade ProfileOverview:
Generic information on airfoils, which could be applicable to the SynchroLite and UniCopter.
Data, notes and comparisons on NACA 00xx, NACA 8-H-12, VR-x, VR-7b and NACA 230 series airfoils.
Plus Wortmann FX 74-CL5-140 for inverted use as horizontal stabilizer on UniCopter.

Note:
All of the above airfoils can be plotted c/w coefficients on NVFoil freeware program.
There is a lot of airfoil data at this site; AID ~ Airfoil Investigation Database
Description:
A very comprehensive and current database on 1,755 airfoils. It is based on the University of Illinois airfoil database but with considerably more information on each airfoil, plus the ability to directly compare airfoils.The 3 following graphs compare the 4 listed airfoils. The horizontal axis is Angle of Attack [alpha].
See bottom of this page for data on specific airfoils
