For throttles, I'm a fan of turning down the end point adjustment to about 1/2 on the low end and up all the way on the high end. Then I adjust the servo horn and linkages to work properly with that range, adding throw to the low end if needed to get enough travel. That will mean 1/2 stick will give you 1/4 -1/3 throttle, which is just about right for a linear RPM response. Setting it up that way gives you finer control over the lower throttle settings, which is nice for getting your landings right. Of course, that's with engine equipped planes. I just set up for linear control on electrics.
