To set the throttle slider to zoom do that in the lockon controls panel (lockon, options, Input, X52, ) not the x52 profile Same with the pitch and roll however I found those dials way to sensitive. I had my pitch and trim set to my #1 hat switch and pinkie trigger.
I had that front wheel set to roll down = #7 ground weapons. Roll up #6 close air to air and press for guns. Alas I lost my profiles when my Mother board died so I am having to rebuild mine from scratch
