Hi, if you are looking for the updated 2010 KOP, it is now located online at: http://www.ptc.com/go/firstkop

On the design can you use ailerons, and where are the pictures of the business jet.

What is the AC location on the tail sizing spreadsheet?? We are also having problems with flow.edf, we have done the fix from the video and are still having issues. When we suppress the wing that came with the project we are able to run Flow but if we don't suppress it we get an error saying "there is no fluid volume in the project. Please check geometry or boundary conditions." Any ideas????
