I really don't think it matters. If you use the upturned tips you can build and cover the stab flat and then raise the tips. The other way you're building and covering 3 different pieces. I guess it's just a matter of what you prefer. There may be an aerodynamic advantage for one or the other but that's well beyond my knowledge.

  That's what I've been trying to tell the "lunkheads", use a bit of
  clay to balance and set the glide. They like to "wind-em-up" and see
  what breaks. (;-')

  On my ddesign, it seems to like about the rear of the wing for cg,
  just haven't had a place to test.

  I must have had a senior moment, forgot about tail volume but as i
  have a smaller stab built will try it for kicks. Right now I'm
  limited in motor stick length to what will fit in the carry case.

  Bill, what's your opinion on using the "twin fin" which is a 2" dia
  round cnetered bit film covered on each stab tip rather that the
  "folded" semi upright tips like ion the little square?
