We would like to take this opportunity to extend our heartiest thanks to our sponsors, without whom this project would not be possible:


Predictive Engineering is a mechanical engineering consulting company specializing in finite element analysis (FEA), including computational fluid dynamics, structural analysis, and kinematics modeling. George Laird (PhD Oregon State University) has run numerous analyses of the airflow over a variety of fairing shapes, in search of the lowest drag profile. The result is a drag improvement of about 24% over the Coslinger I design. Please visit
