But do I have wrong type of pots for using with Surface Trims, as these are linear!!
As in Sliding Pots ? like used in the CH Throttles? not a Rotary Pot ? there is a Slider Setting for Axis's for using with those type of throttles/axis but I think you can only use the setting once?
They are rotary and in sim seem to produce a linear effect - just like throttle
A bit confuse...
For trim purpose you should use a linear response pot - that can be rotary or sliding type, like in any other joystick axis. *
What is advisable use for trim is multi-turn - ideally 3 turn type pot, for allow fine adjust of trim. This kind of pot use gears to reduce the knob rotation over pot axis, allowing the desired precision.
* BTW - CH Throttle is "sliding" throttle, but use rotary pot instead a linear (motion) potentiometer their movement suggest.
Thanks for the Clarification Sokol ...I thought I had seen a custom built Throttle using the electronics from a CH Pro Throttle that used a Sliding or Linear Pot like this Sparkfun one:
