Having spent a couple of hours of experimenting, I have come up with what I find a much more controllable throttle in the critical 80% to 94% range. The downside is that you lose a bit of sensitivity in afterburner and in the taxying range, but I don’t find either a problem. You still get the same idle power and max reheat power.
This is for ThrustMaster only, although a similar procedure might work for other throttles You need to go into Controls setup and for each throttle axis select User Curve. Then for each of the 11 settings enter the following values:
0 16 26 32 38 44 50 56 63 77 100
I hope this works for you. Just check that you can still get around 70% with throttles closed, and full afterburner with them fully open.
