Didn't mean to be so blunt. Had my coffees now..
Ive got the warthog as well. What I do is set it as close as possible to the ingame and real world settings. Look at the pictures in the manual and copy what you see, for example the trim settings and pneumatic brake, etc. the L-39c is a very basic aircraft and as such, there is not much to map if you want close to reality. Once you get comfortable you may relaize there is something else you want on the HOTAS, such as trim reset or possibly set the throttle stop/idle button to your throttle gear warning cancel button.
