How to Taxi on the ground using a keyboard

[Lonn]

so i love FSX but I haven't found out a reliable way on how to taxi on the ground (I know people can use a Joystick with a Z-Axis to do very sharp turns on a taxi but while i use the mouse because i have no access to a joystick i can only make medium turns. i sometimes the the rudder keys to help but if i do use them they "stick" to one side until i press the opposite key, is there anyway to make it so that the Control Axis automatically move back to the default position without me having to over correct for them (On a joy if you let go it will return to normal) is there anyway to replicate that on an aircraft?

Try differential braking for sharp turns. It is how some planes make sharp turns in real life. If you want a hard right turn, press down on the right brake only. As for the rudder, try auto-centering it by pressing the #5 keypad button with the Num Lock off (default control). It's not automatic but if you are already using the 0 and Enter keys it should be a quick key press.
