Unless I missed it the rules it says nothing about your MAC "will or must" be per the recommendation. I talked to Lewis about this since a few people will be flying the large f-14 at his event. If this was a requirement the only way it would be legal was if they moved there stabs or some kind of mod. I guess AMA said it was not a rule just a guidline, I will call monday and ask myself.
The section F does talk about servo torque and arms to allow for full defection but does not say anything stating the MAC will be per the diagram.

How do you figure that?
