QUOTE(jcb29 @ Jun 20 2010, 07:56 PM) Yep, I've read that site and all of its attachments is great detail. There are many figures provided with a lot of relative differences between various configurations of a 914. However, while the formulas included reference frontal area, there are no values for area provided. So I'm still looking... does anyone know the CdA or the frontal area of a 914? Thanks, Eric |
