Ah....Ok, I see what you are doing! But, again...by reducing the endpoint (ie: ATV) instead of setting you linkage geometry correctly for Full Up/Full Down deflection reduces the available torque and holding power of the servos. Since P-mix 7 does not have many applications for our Jet needs, this is probably a better solution since it will not affect your linkage geometry nor will an adjustment to center switch position flap deflection change your flap up and full down deflections.
