Bridi XLT Anhedral

[ronlock]

Anhedral stabs were popular on many pattern birds in the 1980's.
Then it started going away - Dave Brown's Illusion had less
anhedral than most, I understood the intention was a more
stable plane in gusty air.   The Tippos lost the anhedral 
around the same time.

  If my memory serves me correctly, and it seems to fade often <g> anhedral stabilizer resulted in the plane porposing in cross winds.

  I think this was the discussion many years ago. I'm not sure how much cross wind it took...

  Perhaps some of the others will recall this as well...

    Working on a Bridi XLT; the stabilizer has anhedral, and the wing has dihedral (with the wing upside down, there's about a 3/4 inch gap at the center). Comparing the XLT with  Bridi Great Escape, the Great Escape has a straight stabilizer, and a wing which has a top surface that is flat (minimal dihedral).

    Question #1: What are the characteristics of the straight vs. anhedral stabilizer, and how does either apply to the amount of dihedral in the wing?

    Question #2: With the anhedral stabilizer (on the XLT), what kind of mixing can be expected in point rolls and knife edge?

    Thanks!
