(I have a thrustmaster hotas x) as have no real flight sim experience. Controls are very twitchy/sensitive to me.
You should be able to adjust the sensitivity settings, either in-game or in the config software for the HOTAS.
I would really like to get into it, so can someone give me the best place to go for a noobs starting guide and a few initial goals that will help me get a foot in the door.
There are training exercises and videos linked from the main menu, which would be the best place to start.
There are a couple of articles on the FD forums worth reading, as well as plenty of YouTube guides.
Some decent tips on setting up controller would be great too
Most controllers have a profile already built in, but mainly it's down to your own preferences.
You'll want to assign anything you need immediately to the HOTAS (flight controls, weapons, targetting, etc) and the rest can be put wherever you like on the keyboard, such as landing gear, lights, etc.
Remember, you can set up one or more buttons as a modifier, so a 4-way hat gets another 4 controls for each modifier you set.
What is currently the go to ship for long range exploration?
Anything with Explorer in the title is a good start - Asp and Diamondback, for example. Upgrading things like the power plant and FSD drive will beef up your jump range.
The Diamondback is cheaper (mine has over 30Ly already), but carries less weaponry and has fewer internal slots.
