Zenith 601 HD
I owned our Zodiac 601 UL TD three and a half years and I should have put VG's on it 4 years ago, the plane weighs 550 lb empty but was alway's flying nose, high not any more
I put the feathers as per instructions on the wings and also put two on each side facing slightly down 2 inch above the wing on near the leading edge and one were the fuselage bends inward .
then I also put 14 vg.s on top of the canopy to keep the air attached to it and not become turbulent
10 MPH drop in stall speed is a lot . now every landing is tail wheel first. and the plane just fly's like on rails.
Thanks for a great product
