I have new Futabe S9372SV servo I put on the T/B of a new Team Durango DNX8 but it’s “twitchy”.

I called Futaba and asked them about it and he said I could move the arm 1 tooth over to relieve it of the spring on the throttle linkage but that would leave my carb open too far instead of have a proper idle.

He also said it is a programmable servo and using a CIU-2 tool, I could program that out of it so the servo’s neutral position would be where I want it pushing on the spring a little, keeping the carb closed, and not twitching anymore.

Reading all the documentation I could find, I don’t see anything about specific programming.

Anybody ever program servos before?
How does that work exactly?
