Figure you pattern guys can help me out here.
Background - competed some, but years ago. It left me with a strong yearning to fly in 'pattern' fashion rather than just ambling a model around the sky while tossing in the odd loop or roll.
I also have this really strange quirk - I design my own models
Down to business - after years of using basically two airfoils on my OD (Own Design) models, I think I could do better.
So - what are the favoured airfoils for 'pattern' type models these days? I can handle CAD and Profili, but date back to drawing airfoils off percentage chords and above/below chord line dimensions, so should be able to draw a symmetrical airfoil up from most sources.
Thank you in advance,
