Kitfox Tuft Testing

My Kitfox Model 2 with wool tufts on the upper wing surface to test the stall characteristics before installing vortex generators. Stall progresses out the wing from root to tip as designed although it's hard to get the tip to finally stall. Sequence is takeoff, climbout, the stalls including a deeper one where the tip finally stalls and the plane falls off in roll before recovery, followed by a flyby of my hangar and then approach/landing. Notice how fabric appears loose and flutters/oil cans, especially toward the wing root. Couldn't tell if this was just loose fabric, bad turbulence at the boundary layer, or natural flexing of the wing. See followup vid with vortex generators installed for more on this problem.
