REFLECTOR:Aileron Fence

[Rene Dugas]

I would be interested in dimensions and locations  of fences.
Thanks,

Hi Chuck,

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.  I
think everyone should move to forward hinging doors;)

Rodney Brim,
PS I have a picture and dimensions if you want them.  They probably
helped
save my neck as I had an ugly door pop, going inverted stall at 200 feet
coming off a runway a couple of years ago... sometimes you can use all
the
stability and directional control you can get your hands on.

>From the Newsletter, some preliminary flight testing seemed to show
than an
inboard aileron fence had merit for reducing takeoff distance,
increasing
climb rate and perhaps reducing stall speed while not affecting cruise
performance and turning characteristics.  Has this become a concensus or
is
the jury still out?  And, is there a standard template for such a fence?
