about it...lol<br>
<br>
The reality is the throw is just more linear. With an arm, even though
the attachment point of the cable to the arm still moves in a circular fashion
(same as the wheel), the cable is not following the arc. So the angle of
the cable is changing, and the relative throw is decreasing as the arm is deflecting.<br>
<br>
Can you tell??? Well, it’s effectively giving you opposite expo (the arm
is). Meaning the throw is more sensitive around neutral.
When we used Analog servos...this was actually a good thing.
The amount of blow back on our barn door rudders made the first bit of
movement somewhat ineffective. But now with the digital servos which
operate at full torque even near center, my guess is that people running an arm
MIGHT...just MIGHT use slightly more expo on their rudder to offset the mechanical
negative expo. That’s if they really notice it.<br>
<br>
I just go for the bling. :)<br>
