[rebel-builders] Moose: vortex generators

Ross,

Quite a few Moose have VG's. Most mounted at 10% chord if I recall
correctly. Mine are from PNW Aero out of Oregon. I believe the VG's add
slow-speed control (e.g. better aileron authority). The VG's probably
reduce the landing speed some. My Moose doesn't really stall (no noticable
break that is)--it simply continues to drop about 700 fpm with the stick all
the way back and about 25* flaps indicating approximately 48 mph.

Ted

Has anyone put Vortex Generators on their Moose, and are there any
documented performance data to support the results?

Thanks Ted. I have a fair amount of time in a C-180, with and without VGs, and your assessment matches what I've found with the 180, which makes it well worth the time and expense to add them to my Moose project.
