REFLECTOR:Aileron Fence

[Scott Derrick]

First bubble to pop is that the aileron fence will not reduce your 
"planes" stall speed, that's determined by your canard. It would reduce 
the stall speed of the main wing thus providing an even bigger margin 
against a Deep Stall.

Klaus S. did some testing of this on a long EZ and had good results for 
increasing lift which would increase your climb rate.  It is also 
supposed to increase effectiveness of the ailerons at slow speed. 
Search for "Klaus lightspeed" and he has a web page describing the tests 
and results.

I don't know about takeoff distance since your canard will still want to 
fly at the same speed.

If you want to get better take off performance, climb performance, 
better aileron effectiveness I would highly recommend installing VG's on 
the main wing and canard.

The factory has tested layout templets.  YOu can buy the VG's from the 
factory of from Computer Certainty(I recommend these).
