Okay, since there is another discussion on the service alert regarding major changes to a wing upon which I brought up VGs, I didn't want to high-jack that thread so, I'm waking up this message to ask my question.

What are the pros and cons of VGs on a Kitfox 5-6-7? I understand what they do and given a no flaps stall speed of 44 power off stall and 42 power on, how beneficial are these to the Kitfox. I saw that Papua Flyer is thinking about adding them. I've seen them on other KFs via YouTube videos. Are these worth the cost and time?

If so, what brand/source is good for them?

Washing my wing leading edges (I do this after every flight) is the one and only reason I hesitate to install VG's.

Really?? My airport is located next to Utah lake, with a population of trillions to the tenth power of bugs. Basically anytime other than winter you can plan on getting plastered by bugs, BIG ones. Enough bugs that the plane will smell like dead fish when it’s in the hangar. I wipe down my plane after every flight and having vgs adds virtually no time maybe a min at most. The bugs impact the leading edge and underside and rarely impact vgs. I think in the 100 hours I have one or two bugs hit a vg. I have flown without vgs for a season and with vgs for a season and have zero regrets or have it negatively effect cleaning. Along with that point, those that are clean ocd like myself, ceramic coating makes wiping the bugs off about a 5 min post flight job.
