Glen,

Thanks for the link; I built adjustable stabs on both of my Aries using the Bob Noll approach (which is what it looks like Earl used). My real question was what people were doing on the Impact to #1 make the stab adjustable and #2 cause it to be weaker. Perhaps Andy's reply identifies the issue, I guess because the Impact already has the holes in the stab for the rear anti-rotation pin, people must be putting the adjusting mechanism on the fuse rather than on the wing, as is done for the primary wing.

Will you be flying an Impact this year?
