Configs & Templates || Dual Rate switch?

Hi Folks

Ok bear with me I'm learning

Trying to figure out what switch is mapped to dual rate...assuming that the dual rate template means there's a "beginner mode" and an "advanced mode" that adjusts the servo throws and speed.

In the 4Ch DR template..... where's the link to what switch actually controls dual rate? Or is this simply a template for the LOW setting in Dual Rate, and just use the regular 4CH model for high rate? (basically, have 2 models for the same aircraft?

I can see where the mixer has a scalar=60 which I'm guessing is the actual limiter....

Is there a way to write a model so that it has high rate and low rate, controlled via a switch? or am I just missing something in the config? Loading a new model to land may cause some....issues LOL.

neg=TRIMLV-
[trim2]

neg=TRIMRV-
[trim3]

neg=TRIMLH-
[trim4]

As always, thank you sir! I'll go digging in. I've got the jumper, so I need to check the switch settings.
