Does anybody know if there has been any flow and tunnel testing on various wingtip designs for aircraft opperating in our speed ranges. This year I would like to begine testing different wingtips on my plane (they are removable) to see what works but I need some basic design info on different models. If I build a couple different tips I can change them out on the same day and get better test results - same plane - same day - for real life comparissons.
Thoughts? Thanks - Bill
