Wingtip Stall Fences

[EDMO 1078]

Randy,  With the plates located at the end of your wingtips you wont have to worry about this, but as a CAUTION to others thinking of experimenting by removing wingtips and replacing them with flat plates on the end of the wings this might apply:  "The ailerons (same as flaperons) should not extend to the end of the wingtips because the vortex there can induce a flutter on the ailerons."  "The Design of the Aeroplane" by Darrol Stinton.  

Attaching a page of tip designs from his book that only deal with vortex and drag - nothing to do with STOL, as I understand it.  However, he does say that the wider the distance between tip vortexes the more lift is produced for shorter takeoff and slower landings, which is also the conclusion that long wings have more lift than short wings.  The "Finch" tips are in another book that is about drag and vortexes.
