hi brian,

i didn't realize the tangent points i added were wrong until you pointed it out. i did two checks, but was zoomed out to much to see the error. they had round-off error because i reduced them to the naca three decimal format. so i increased them to the max moi allows. that should fix the problem. but doing it the way you have it now is fine. it should be just as accurate. sorry i was too late to save you all the added coding. but it seems like you enjoyed the process of learning moi scripting.

i look forward to the next version.
