Default Throw measurement on tapered control surfaces

When measuring a control surface deflection (throw) do you measure at the tip or root on a tapered surface? If measuring degrees then it doesn't matter, but most manuals reference inches of deflection. Thanks.

surf,

What I normally do is hold a ruler vertical to the TE of the control surface and then move the stick both ways and adjust everything machanically as close as I can get it and then If it needs a little tweaking I use my end point adjustment. You don't have to be exact on the measurements, just get it close and once your in the air you'll know if you need a little more or a little less and once you land you can use your end point adjustment again. Don't forget to set your Expo.

On the one's I've had, the deflection is measured at the widest part of the control surface.

So widest part of the surface (typically the fus end). I know it doesn't matter that much as you will adjust throw to your liking, but I always like to start where the manufacture recommends. Thanks for the replys.
