What Al is describing is the top shape of the canard fastbuild wing as
it was made by Wingco (Alan Shaw).  Wingco added greater camber to the
canard, so much so that the standard canard incidence jig would not fit
the shape of the wing (the jig at that time was in the shape of the
upper airfoil).  To get the incidence jig to work, builders needed to
add a "popcycle stick" or tongue stick to both the forward and rearward
point where the jig contacted the wing.  This raised the jig enough to
allow it to measure incidence, but not pivot or 'rock' on the apex of
the canard upper airfoil.  If I'm not making sense, its because I just
had some great wine with lasagna tonight.  The canard incidence has
always been the same.  The popcycle stick thing was only used on Wingco
canards and only to get the jig to sit above the apex of the higher
camber put into the canard by Wingco.

This is a possible issue for me too.  Um, Scott B can you jump in here?
Has the factory always had the very same recommended canard incidence?
Or has it changed over the years?  ...or is there a range of degrees
considered to be acceptable based on combination factors once in the
flight test phase?
Thanks,
Terry

HI AL

The factory advised us to use two mixing sticks under the wingco canard
gage on our XL.

Hi, Mack;

 

Can you tell me more specifically where/how you placed the sticks.  It
will give me a better idea of how much of a change may be necessary. Two
sticks is about 1/8".  And where did you place the gauge?  With the
varying camber from center to tip, there is only one place where the
gauge fits the coutour.  On mine it was about 2' in from the outboard
end.

 

When I was installing the canard some years ago, I spoke with both Alan
and Mark Machado at Velocity, and neither suggested anything different
about the use of the incidence gauge.

 

Thanks,

 

Al
