Hi Thomas,

Thanks for the AMA Info. I used that diagram to design the canards and servo system on my Sabre XLT jet a few years ago but forgot about it.

Here’s what it says: The pivot point for the control surface can be determined using the diagram below as long as the pivot point is ahead of the 25% Mean Aerodynamic Chord (MAC) point by 2%-4%.

So that’s a pivot point at 21-23% MAC. Which is better, Is that really valid, and where does the info come from other than AMA LMA document?

Thanks,
Gary
