This is what I have for the TCA Quadrant Throttle file. You can locate it at:  C:\Users\yourname\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\packages\inibuilds-aircraft-a300-600\work 

You can try these settings and see if this would stop the reverse thrust on idle. For me it does work. Hope this helps you all. 

[throttle]
reverse_on_axis = true

[throttle_1]
reverse_1 = -0.987500
reverse_idle_1 = -0.727063
idle_1 = -0.574902
toga_1 = 1.000000

[throttle_2]
reverse_1 = -0.987500
reverse_idle_1 = -0.727917
idle_1 = -0.576001
toga_1 = 1.000000

I have this one as well it works 

 

[throttle]
reverse_on_axis = true

[throttle_1]
reverse_1 = -0.987500
reverse_idle_1 = -0.591687
idle_1 = -0.517896
toga_1 = 1.000000

[throttle_2]
reverse_1 = -0.987500
reverse_idle_1 = -0.586438
idle_1 = -0.527051
toga_1 = 1.000000

In general, make sure that the value for "reverse_idle_1 " is about 0.05 lower than the value for "idle_1",

for example: 

idle_1 = -0.50

reverse_idle_1 = -0.55

This way, the throttles will have a small but sufficient dead zone to switch from reverse to forward thrust. This solution also works fine with inibuilds' A310.

 

Happy flying!

 

Thanks y'all!
