+1. you need to be able to mechanically close the venturi barrel completely.
that throttle stop screw is often overlooked.
I do fly Nitro / Gas as well as electrics (dabble in heli's too) and have never used a throttle curve on anything but heli's.
as has been mentioned:
Set the throttle servo so that you've got a good reliable idle with the stick at idle, but still have enough trim authority to shut the engine down with the trim lever /kill switch.
(I also totally agree, I WISH TX manufacturers would leave the old mechanical / analog trim lever specifically on the throttle)
if they did that though, I'd have nothing to complain about

the kill switch
will not work because there is no more room mechanically for the throttle arm to close. This is why I ask what is better.
If what you mean by this is the throttle barrel does not completely close then you need to confirm that whatever your engine is, that if there is a throttle stop screw on the carburator, it is not stopping the barrel from closing completely. In other words without any pushrods connected to the carbs throttle arm that when you move the arm to closed position and look down the hole (Venturi) the barrel is completely closed. Many engines come with throttle stop screws that the fellows often ignore this.
