I am trying to select and airfoil for my A-level Dt project, the build thread can be seen [link=http://www.rcuniverse.com/forum/m_8547717/anchors_8547717/mpage_1/key_/anchor/tm.htm#8547717]here[/link].
The details and requirements of the design are a 40" or so wingspan with a tapered 2 piece wing (much like the sebart katana and sukhoi 30 size wings)
the model must be able to perform 3D aerobatics well, and also be able to perform smooth aerobatics to a reasonable standard, like the EF vanquish and sebart katana 30. I have been looking at different airfoil types but Im really not sure which one would be best for this project, seeing as its quite a crucial part of the models flight characteristics and overall performance I figured I would ask here.
I have the program Mac foil so all I need is the data file for the particular airfoil type and I can plot the foam cutting templates from that.
So in short which airfoil type do you think would be best suited to my project, being tapered, able to perform hardcore 3D yet fly reasonably smoothly aswell.

Thanks in advance
Michael.
