also what is a good plotting software that is free to plot the airfoil on?

do you know how thick the airfoil is?

Its probably the stock E-205, besides, can you change the percentage of thickness without registration?

Just checked, there is two in Profili;

The first is 10.5% thick with a 3% camber,
The second(I'd choose) is 9.5% thick with 2.5% camber.

Go faster with the one with less camber and thinner percentage!

When I compare the airfoil section at the plan with E205 provided with Profili it didn't match.
Have I made a mistake, or isn't it E205

The airfoil you end up with when you build a Talon will be anything but the intended E 205. It's a built up wing with die cutting that leaves something to be desired IMO. If you're going to have a wing cut, you might want to ask instead for a suggested wing section for this bird. The E 205 may or may not be the best choice.

You could try an E214...

E205 isn't my choice for the airfoil.
I doubt whether I take the original (kit) airfoil or something like RG15.
The first is easy to construct for a build-up wing, the second is better, but more complicated to build...

The die-cut ribs seems to me not very accurate, so I'm searching for the original airfoil, so I can use Profili for printing them.

Understood Wouter, but my post was directed at the thread starter. The E 205 may well have been selected because it is easier to reproduce in a reasonably accurate form when built up. My point is that since the thread starter is getting a foam core cut, he need not limit himself to the stock airfoil...it is entirely possible that a different airfoil may show performance gains. I think the designer of the Talon posts these boards on occasion. Hopefully he'll chime in on the orignial airfoil of this plane???...before it went in to production as the Talon.
