Changing the Min value of the throttle servo, will also not allow you to move it more in Manual mode, so take that for what it is. 
THROTTLE_SLEW is the minimum time it would take for the AC to go from 0% to 100% throttle.  It is linearize as well I believe.  This is so the engine doesnt make very erratic changes, smooths it out.  Probably good for the turbine.

First of all have a happy new year with health for all.
To my question now...
I am getting ready to fly a turbine powered Paparazzi equipped jet
and i need to ask a question before the actual take off
( )
This is not my first paparazzi equipped plane but all the previous had
electric power plants and i am unsure about the throttle settings.
The wiki says that a simple variable is needed in order to set the
idle/kill setting but i don't know if setting the
<servo name="THROTTLE" no="2" min="950" neutral="1100" max="2050"/>
will be enough or something else/more is needed.
Maybe i should set the "min" setting to the idle value of 1100 ms also
just to be sure that the
turbine will not shut down accidentally?
Also i would like to ask if setting the
<define name="THROTTLE_SLEW" value="5.0"/>
will notify the autopilot that the turbine has slow acceleration so
it won't make fast pitch changes as it takes 5 seconds to get from idle
to full power.
Thank you very much.
