How to slow down Spartan gyro on Trex-600
My setup: Trex-600ESP 6s setup and Spartan gyro with 9256 servo.

Problem: the tail is too wild. I apply a little and it goes almost 180 degree in IDL2. I went to my 10C radio to add some expo, but it didn't have any effect. I guess the Spartan can't be adjusted via radio. In the Spartan config screen, it shows the below:

Rudder stick deadband: 5
Mode 2 (AVCS) - this is what I fly
Acceleration profile: the bar is at the 2nd notch next to "Fast"
Deceleration profile: the bar is at the 2nd notch next to "Fast"

Clockwise stop gain: 120
Counter clockwise stop gain: 120

Rudder Exponential: -40
Rudder Sensitivity: 100

How do I make it to be more controllable? Thanks in advance.

I use my dual rates.I also like using the switch for different tail performance.Love that setup

I will try lowering my EPA when I'm at the field again.

For the value (Rudder Exponential: -40), did I make it worse and more twitchy with that negative value? If so, I need to at least start with a zero value before making it a positive number?

Negative expo will make it MORE sensitive. At least it does when applied to cyclic. I have never used neg. expo on rudder, but I would assume it is the same. To make the stick less sensitive around center you want to INCREASE your expo. Try making it positive. I would start around 10% -20% or so because 40% might make it sluggish. Good Luck!Procrastinators of the world unite ... tomorrow.

Thank you very much. From reading the text when hovering the mouse over the value, it says
You may adjust this value between the range -100 to 100. Negative values make rudder control more precise in around mid stick. As this adjustment is set higher, the gyro will respond more aggressively to the rudder stick change movements.
Am I reading that the positive number will make it more aggressive?

Futaba - negative expo tames it down around center
JR - positive expo tames it down around center

No matter which brand, for any Heading Hold gyro, lowering the maximum throw will slow the rotation speed. You can do this by lowering the end points or by lowering the dual rate number. If you use the dual rate method, you only change one number to change both left and right rotation. If you use the end points, then you can independently change the left or right rotation speed.
