There are a few essential controls that don't have default keys assigned for sure, calibrating your stick shouldn't be necessary but your axes may not be recognised by default either.
Try this, go into control settings select 'aircraft' then 'axes', click on the relevant axes you want to set and give your stick a wiggle in the appropriate direction. Rinse and repeat until all your axes are set, and don't what ever you do exit the controls menu without clicking 'Apply' in the bottom right. If you don't you'll have to go back and start again!
Try this and post back if you need more help, also post your specs as well.
