Please add me to the list of those wanting pictures and dimensions of the
fences!

 Here's Rodney's results on a Velocity: Rodney's fences are pretty big.

 1. I got a >15% reduction in take-off roll on my final version of the
 fences.  Looks like that is attributable to driving the air more directly
 over the wing at slower speeds and not having it slide down the wing, which
 if you do some dirty oil tests you will see that it is doing.
 2. It doesn't effect your stall, that's all governed by the canard.
 3. It feels like it reduces roll rate slightly.  I didn't measure it, but
 you can tell the plane has more tail feathers, especially as you move the
 fences out along the wing, which I would not suggest.  To me it makes the
 plane feel more stable.
 4. Reduction in cruise speed is dependent upon height of the fences and
 location.  At the location and height I have them, I have no reduction in
 cruise speed.

> 5. I think they should be standard on the kit... but then what do I know.
