GP Cessna 182 airfoil
Hi,
I would like to build a new wing for my 182. I should have copied the airfoil before putting the wing together but was in a rush to fly it. The reason I want the airfoil type is so I can build a up a wing for it that has flapa. Finished up with an os .46 for power it weighs in a a little over six pounds. It lands far to fast for me to feel comfortable with given our field is crowded ont the weekends.
Thanks

We're sorry, but we don't have an airfoil plan for the Great Planes Cessna 182 ARF.
What you can do, though, is take a piece of card stock, or even file folder. Cut one edge absolutely straight, then make knife cuts every 1/4" perpendicular to the straight edge. Now you can fold each of those small tabs so that the piece of card stock fits against the top of the airfoil. Do the same for the bottom. Now you have very close representations of the top and bottom airfoils. Transfer this to another piece of paper and clean up the lines into smooth curves. You can cut them out to compare with the top and bottom and "clean up" any small discrepancies. This gives you the external airfoil. Allow for 1/16" or 3/32"sheeting, leading and trailing edges, and you have a rib profile.

Thanks,
I will measure the contour I had hoped to get the airfoil number and just plot the design. But might I sugest that they may want to incorporate flaps into this mode. It would make it a much better performing aircraft given the wing loading. I would also say that the ca hinges on the struts are not up to the task mine have failed twice already and have since been replaced with a metal strut system.
Thanks,
