Please do not post multiple copies of the same thread in several forums- that is known as spamming and tends to irritate other members. I have moved this thread to the appropriate forum and deleted the other copies which have not generated any replies.

Polars are graphs the explain how the airfoil works at different speed, angles etc.
You can see how much it lift, drag, and want to rotate... this in very basic term.
Analysing Polars is very important for understand what airfoil to use for our projects.
