Default Setting control surface throw.

Use the servo and control surface arms/horns to set design throw with max on servo arm and min on control surface horn, or the opposite, or a little of both?
Set midpoint on both servo and control surface horn and use dual rate on transmitter to set throws?
Or something else?
It is confusing for a newbie.

It depends on the plane to a point. I am going to assume you have something mild like a trainer. Put the rod in the servo arm as far away from the servo as possible when using a stock length arm. On the surface end also connect as far out as possible. This is the ideal set up for the surface end as it gives the push rod the most leverage. It's not ideal for the servo end as it takes the most effort for the servo to push and hold the surface. However most of us use more servo strength than needed and you should be fine.
Dual rates are also not a bad idea. But be careful here also. I used to set mine up as follows. I am a thumb flyer and just flying around my sticks rarely move far from center. The sticks probably never move more than the size of a nickel. SO when setting up dual rates I have max throw on high rate. Then to set the low rate I use a combination of expo and dual rate. I turn the plane on and move the stick to the size of a nickle away from center. Then adjust the rate so matter which position the dual rate switch is set to the surface moves the same amount at this stick movement. This is done so if you accidentally take off with the switch in the wrong position the plane will fly the same. I've been flying many years and only fly on high rate now with lots of expo. For a beginer though as I suggested above is a safe way to do it.

Set the midpoints as close as possible mechanically with radio trim at zero and endpoints at 100%. Then fine tune everything using the radio's trim and endpoint settings on the dual rate HIGH setting. Finally set the dual rate LOW settings on the radio.
