When your buy the VG's kit from Zenith they send installation instructions and drawings with the VG's. The drawing shows placement for the elevator of all STOL CH701 / CH750 / CH801 series aircraft.

I do know the the exact locations. I have enough material to make the VG's myself, so I only need the drawing. Maybe you know where I can get it or buy?

You can buy the kit from Zenith. Very easy to install and best thing I did to my CH701. All my landings are 10 out of 10 now.

From what I have read, the VG's are no help or substitute for slats. Have a look at

Good luck.

I believe you guys are talking about vg's on the wings and the original post is about vg's on the elevator which helps with elevator authority at high angle of attack and low speed.

I'm sorry Allen and the others, I thought you guys were talking about the VG's on the wing. Now if you mean the VG's on the elevator, the short answer is excellent. I put them on my elevator and now all my landings are 10/10. Before the VGs I had to arrest the sink by power at the flare out to land gently and now I can land with no power and can pull up the nose and gently land. The best thing I did on my CH701. Hope this helps Mike from South Africa.
