Next plane is a Quad City Challenger 2 long wing. Put these on during the build. Wings are the standard PolyFiber polyester build through PolyTone top coat. VGs on the wings, both sides of the rudder at the hinge line, and the bottom of the vertical stabilizers at the hinge line. Excellent slow-speed stability. Highly recommend these.

Put a set of these on an Aerolite 103 which has Dacron sailcloth wing covers. Used JB Weld PlasticWeld and have not lost one in the ten flight hours they have so far. Took not quite two hours to install them. I dont have hard numbers, but no-flaps climb-outs feel a shade slower. Might just be the weather getting hotter. Where these really shine, though, is on final with full flaps. Im landing 8 MPH slower and these things make the wings stick to the descent like glue. Very impressive improvement. Highly recommended. Will definitely put them on the next plane.

Installed these on a QuadCity Challenger2 short wing. They work great, made the aircraft very stable in stol operations.

I bought a set of these and put them on the wings of my RV-7, they worked perfectly. My airplane stalled around 60 mph and would depart flight by one wing dropping. With these vg’s it would not stall. At a 45 degree angle and 1000 rpm it was backing down very slowly 50 mph. It never tried to stall, one wing would burble a little and with a minimum of control input it would stop the burble. I checked the top speed and it did not effect it at all. At 183 mph they started to blow off the wing. They were attached with carpet tape. Trust me, carpet tape want hold up at 183 mph. Good product. I have ordered another set to replace the ones that blew off. Loctite 401 this time.

I put these on my Pelican Pl turbo, they work great but the only problem I encountered is the sun, they get brittle and break off so you have to replace them
