Default Why the long servo arms

Why the long servo arms like on the rudder. I'v got a goldwing 30cc mx2 and using the kits supplied servo control horns. I had to really cut my end point adjustments back on my 9C.
On my rudder I had to cut my epa's from 140 down to 65 for full deflection.
My servo's are the GOTECK 5515's and they have control arms that are a little longer than your standard arms so I elected to use them. Now my epa's on my rudder are a 98 and a 100 for left and right

Long servo arms, if working with long control horns have lower rod forces.



Long servo arms with shorter control horns have more control surface deflection.



On the negative side, there will be more torque exerted on the servo, so it needs to be stronger. The gears need to be up to the task as well.

And long arms and horns tend to negate any chance of flutter
