Try setting it up like so.
Turn the micro stick into a mouse. I originally did this for map moving and turret aiming in IL2 sturmovik but soon found it worked quite nicely for lomac. Adjust the sensitivity to what you like. Do the same for the X axis.
The reason THIS (using it as a mouse) works better than setting it up as a DX stick for the maverick TDS is that it stays in the position you leave it in. I use this for all my BVR TDS aswell.
What's also great is that it allows you to move the TDS diagonally (unlike if you are using buttons). IF however the thumb stick is simply uncomfortable for you, you could try using the Hat switch on the Combat stick. I would recommend the thumb stick for TDS in all aircraft and hat switch for scan zones in the fighters/interceptors.
Happy hunting
