Thanks guys! Glad you guys liked it, I will try to keep doing videos like this as well as my regular edits with only music and not me talking the whole time.
I never flew the wing without them. The previous owner said they really didn't do anything to the stall speed, maybe a little more stable on approach but he said the difference wasn't really discernable. I wish they were taped on instead of glued, I would really like to move them forward and see how they do, the placement of them now seems too far back to even have any effect at a stall AOA.
