REFLECTOR: canard question

[Al Gietzen]

Gregore;

 

I'd suggest placing the incidence gauge (presumably a.k.a. canard rigging
board) about mid span on either side of the fuselage, and get the average of
the two readings to be centered.  Perfection is not a requirement as there
is likely to be more variation from one canard to another than the
differences you're seeing on your gauge.

 

You may like to read the slightly different procedure that I used to fit
things up at http://members.cox.net/alg3/canmt.htm. 

 

Best of luck,

 

Al

I'm just about to install the bushings for the canard lifts, but I had a
hard time to level the canard perfectly.

 

It is level both left-right and with respect to the distance to the spar,
but it is stubborn to get perfectly level with respect to the "incidence
block".  BTW, my kit came with a part called "canard rigging board", while
the manual mentions using an "incidence block" to level the canard; are
these the same thing?? 

 

So my problem is the following: no matter how much and where I shim it, some
parts of the canard will be level wrt the indicence block, while others will
be slightly off; the differences are not big (for example, the air ball is
still in between the black lines), but I'd like it to be perfect. 

 

I bought a fast built kit, so the canard came already made.  Analyzing it
carefully, it appears that it is not perfect, it is slightly bent is some
places.

 

Is this something I should worry about right now, or it can be finely-tuned
later?  Where is it more important to be perfectly level, next to the
fuselage/lifts, or towards its endings?

 

Thank you,

Grigore
