http://bf3.realmware.co.uk/ I only use the BF3 settings editor. allows you to edit the user.cfg in a simple way. you can change any setting without having to load the game, like sound, graphics, and key bindings. also provides fixes for things, like unbinding keys that you cant seem to do in the game. also shows some bindings the game doesnt show, like a "light brake" and "heavy brake" for jets and seperate mouse sensetivity for soldier and vehicle. check it out.
I had an older version (of the editor) that I didn't really use I guess. Version 2.3 is very useful though. I tried it so I could see what the difference was between light brake/heavy brake-hover/hover and I'm "deeply impressed". F35 is easy to keep under control like this and seems to fly indeed very easy at about 300/310 Km/H. I spend a whole round in F35 and had a positive KDR.. and that's a first (in F35, not the having a pos. kdr..), won a couple of dogfights, gave the Havoc-pilots a nemesis and I guess that's not bad for a "brand new jet" Again I need to reconfigure my controls.. <div align='center'> :tomcat: </div> Next version of Battlelog Standalone seems sweet as well, now they use a stripped down IE9 but they will change to Chromium for the next version.
I have used the latest version of this app to assign a 'heavy brake' key for jets, it's a pretty decent app.
